So how would you say we do it???
The only people that NEVER make a mistake are the ones that NEVER DO ANYTHING!
Plus, it isn't as if the folks we chase list their name, DOB, SSN, picture, and address in a big criminal directory... There are times when we have to go on god, but limited information. The real world does not fit into a textbook.
Lets look at the reality:
There are violent criminals that will fight, kill, rape...etc and they must be arrested.
We as LEOS are charged with making that arrest.
In order to make those arrests, we must go to where they are which includes their house, car, job etc.
They will often resist our arrest attempt with violence IE gunfire.
Because of this, we counter their threat with weapons and the element of surprise...the latter being very very important if you want the LEOs to stay alive.
If we give up either the weapons (SMGs, Flashbangs, armor...) or the element of surprise, then we are actively compromising the safety of the officers. All of those tools have a specific purpose and that purpose is to affect the arrest safely.
When you demand mistake free humans, you will only get humans that do nothing because that is the only way to guarantee that no mistakes will be made. How many times do people complain that they see cops just sitting around in a coffee shop?
Want to know a little secret? Nobody ever got sued or arrested for sitting in a coffee shop... That is why. It is safer from a career standpoint to just do nothing which is what many of my fellow LEOs do because they got tired of being sued and threatened with arrest. Now, many of us just go hang out at the firehouse and watch movies...or take a nap in an alley. I don't blame them bc I understand how a man with a family would not want to get sued for his kids college money or possibly arrested for defending his own life...
I hear a lot of whining about how LEOs work, but no suggestions from the choir of chairborn rangers...
