do cops in USA shoot first and ask questions later?

No, they attempt to subdue, then if the suspect resists they ramp up their efforts. If the suspect does anything in this state that threatens the safety of the officer, then and only then do they shoot. Which is why most cops get off after shooting someone - the person had it coming. 

You can’t ask questions until you get done shooting, it’s too loud!

It’s somewhat of a tradition. They love guns and that’s one of the reasons they go into that line of work in the first place.

No you don't understand.  We are not a civilized country we are very aggressive has americans.  Then you add guns into the mix what do you expect.  It's not only cops though  many people resist arrest and do not follow orders 

If you were a  cop and don't shoot first, you could be dead,

Some surely do.

Depends if they’re being threatened or not. If their life is in danger at that particular moment, they may have no choice but to act first and then ask questions later. 

No, they do not ask question.

They shoot, and then they shoot some more.

Just watch one excerpt of how cops in other countries behave.

Here in America they get so much scrutiny like real-time scrutiny.

In Russia commandos will burst through the doors of a house and literally kick the crud out of suspects... 

I don't think I have to mention the Middle East.

The thing is?

I think in those places that do not scrutinize law enforcement... they probably have fewer cops/police per capita so maybe there is something?

You have to consider another detail... where this country is obsessed with being "free" and where everything is supposedly up for argument even on the spot.  

There are some situations where you should abide now and contest later... not on the spot.

It's not fun especially if you have been misjudged or perceived incorrectly... but it should pan out. 

whats wrong with that ?

its the american way
