I can see the argument how you would treat a suspect with a gun differently than you would if they have a knife.

However, American cops also use guns against suspects with knives or other weapons that they also use in places like Scotland. Why couldn’t American police use these techniques when the suspect doesn’t have a gun?

I know the standard response is, “well, they COULD have a gun!”, but I don’t think that is a good enough reason to always go straight to extreme response. If a suspect is brandishing a knife, he probably doesn’t also have a gun.

Historically speaking, there were a few shoot-outs in the 80s and 90s. The Hollywood shooting and I think one historically bad incident with cocaine traffickers in Miami - bad days for the police showing up with .38 revolvers and a shotgun or two fighting against a dedicated enemy with AK style weapons and body armor.

The sadly predictable response of the police in America is to overmatch the “enemy.” Presume they have a weapon for crimes of certain classes, obvious violence crimes like kidnapping and also drug crimes, which poor Afroman was accused of both.

Personally, having been SWAT’d as a young man, it’s not that I think they shouldn’t have access to armaments. It’s that their rules of engagement are obscenely lopsided to the point that they just bring them always, all the time, and will not use common sense judgement.

This could have been a knock-and-talk from Officer Friendly and if things didn’t go well - send in a higher level of officer. Starting at bootleg Navy SEAL raids for every accusation is a blight in modern law enforcement.

... how do you know if they have a gun?

As a fun example I had a coworker who collected handguns. I once asked him how many he had and he asked for clarification, should he include unregistered?

Personally I’ve had encounters with LE and have not had a gun drawn yet, so it’s obviously not the default. But I disagree, I think brandishing a knife is already extreme behavior, I don’t think it’s logical to think “because he has a weapon he probably doesn’t have another!”. And why would someone threatening people with a knife deserve benefit of the doubt?
> Personally I’ve had encounters with LE and have not had a gun drawn yet, so it’s obviously not the default.

What does the default have to do with it? We are already not in the default situation. Interacting with police at all is not the default! If you mean to say something like "it's not likely" or "they're not doing it in unreasonable cases" then your anecdote is not relevant.

> And why would someone threatening people with a knife deserve benefit of the doubt?

Several reasons, which would be obvious if you tried to think of them. Most knife-wielding maniacs are, well, maniacs, and aren't fully in control of their actions. Innocent bystanders are regularly killed by police discharging guns accidentally or inappropriately (in fact, even police are frequently killed this way). People are routinely misidentified by police as carrying weapons when they aren't. Police often give misleading or unclear instructions while trying to de-escalate, and with a gun drawn, failure to comply can and does result in the suspect being shot.

Bear in mind that what you are excusing is essentially a (substantially increased likelihood of) extrajudicial execution. It should be a last resort. It's not enough to say "well he's clearly a bad guy, why give him the benefit of the doubt?".

> Innocent bystanders are regularly killed by police discharging guns

False. Innocent bystanders are killed by police discharging guns, but rarely. And, while the goal should be zero, it will never be zero

Personally as a teenager I’ve been met with a group of cops all pointing guns at me when I was just walking around at night with no weapons whatsoever. They got a call from a paranoid homeowner nearby. They’re trained to shoot first and ask questions later.

If this was true, would you have survived?

I got pulled over in Cleveland and had a cop point a gun at me and threaten to shoot - I was apparently wearing the wrong color on the wrong side of town with out-of-state plates and reached for my ID instead of waiting for the cop to tell me to get it. In later stops I've been admonished many times for not preemptively getting out my ID, but I really can't help thinking about almost getting my brains blown out for grabbing my ID too quickly.
I had a rifle pointed at me about a week after I got my first car, because I accidentally drove on the wrong side of the median.

Guns are definitely pulled way more often by the police than they should be. but to your point I am okay with cops shooting anyone brandishing a knife or any other deadly weapon.

In most civilized societies, there's an extremely high chance that somebody wielding a knife doesn't have a gun.
Wielding a knife is a deadly threat so I am not sure what the relevance is.

I had a gun drawn on me and was told “I’m going to blow your f** brains out” because I was a stupid teenager toilet papering a house when I was young. That’s when fight or flight kicks in and logic goes out the window. Needless to say I didn’t fight.
> Personally I’ve had encounters with LE and have not had a gun drawn yet, so it’s obviously not the default.

How police respond to you is very dependent on a lot of factors, including your age, race, what you are wearing, where you are, and what time it is. I don’t think you should use your own personal experience as a universal template.

> And why would someone threatening people with a knife deserve benefit of the doubt?

Because, as a society, we should do everything we can to prevent harm to everyone, even people who are acting erratically. There could be all sorts of reasons for the behavior. Anyone can have a psychotic episode, and that shouldn’t immediately earn a death sentence. Of course, I understand that even an innocent person having a psychotic episode can be very dangerous, and I don’t think they should be allowed to hurt others, and it may be necessary to use force, and potentially deadly force, to protect other people.

However, I think that is very different than saying “we shouldn’t worry about the perpetrators well being at all”, or that it is preferable to kill the person rather than take ANY risk that they could hurt someone. The answer lies somewhere in between.
