Hasbeen,
The "bleeding hearts" know the truth as well as anyone, they know that in the U.S 94% of Black homicides are committed by other Blacks but only 86% of White homicides are committed by other Whites, therefore Blacks kill Whites at twice the rate as vice versa.

A left wing site like The Huffington Post will print that data but still try to spin their narrative around it:

See Hasbeen it's racist to notice these things, it's also racist to not notice or to notice but not speak up about it...or to be ignorant altogether, or to stick your beak into Black affairs, or to not stick your beak in.
It's our fault that Aboriginals get on the grog, beat each other up and end up in jail, but we're racists if we point out that perhaps getting on the grog might be the root cause of such misfortune and not racism.
The "bleeding hearts" are White supremacists at heart who accord non Whites a social status somewhere between children and pet animals, objects who lacking any agency of their own are merely acted upon by those around them.
Watch the videos I linked above, Blacks are by nature egotistical and they seem to have a sixth sense when it comes to condescending behaviour from Whites, hence their taking a hammer to the face of a dotty old hippie who dared to point out that looting for the sake of material gain was "not cool maaan!"
Now you'd expect that the silly old bugger and those like him would realise that Blacks are not objects, that they have agency and will smack you around if you try to interrupt their escapades, but they will always try to find a way to spin getting one's own teeth knocked out into their narrative of racial "oppression':

Heck even a night of brutal rapes and violent beatings at the hands of a Black man can be spun if they try hard enough:

Hi (again) DAVID F...

That's a good question David ? Surprisingly, not many.

(i) The basic 'come alongs' which involve basic wrist manipulations using, pain compliance;

(ii) Disengaging demonstrators who've 'linked their arms together' to avoid arrests, usually engaged in passive demos. With a lot of noise !

(iii) Several 'releases' designed to remove an offender who's trying to strangle you from behind, grabbing your uniform from the front, trying to hold your arms while you're in the process of trying to arrest them.

I must confess, the hardest people of all to effectively control, are women ! Generally speaking when a woman is resisting arrest, they tend to pull out all stops, to prevent you from taking them into custody. Kicking, scratching, biting, punching, spitting, etc. ? Many a large, tough copper, has received injuries from women, including myself. Being bitten quite deeply, on my left shoulder through my shirt, whilst I was trying to arrest her boyfriend/husband. Then off to hospital for tetanus shots, and several stitches ! With 'claret' spreading all over my shirt from the bite site ! Believe me David, it sure hurt ! Women are incredibly violent when they wish to be, despite the illusion of how sweet and nice they can be ?

Further, you have to be very mindful indeed, on how and where you grab a woman while attempting to arrest her. They generally will level all sorts of allegations against you for the manner in which you've touched them ? Including sexual misconduct ! It's good to have plenty of independent witnesses about whenever you have to lay hands on a female ? You can bet your life you'll need them, (witnesses) if the woman's a crook !

Bottom line David, police don't spend nearly enough time training, to learn properly and prepare with the few unarmed techniques they're taught in the Academy. Whereas firearms training is considered paramount for police. Therefore there're many many, hours of practice, which are wholly dedicated for training, for this very important life and death, skill-set ! Hope this helps a bit ?

it is very refreshing to hear it how it is O sung wu. The noise that the Greens make gives the impression that most people believe their constant victim status and lies.

See that's the thing about Police, they're not actually supposed to hurt people in the execution of their duty even when under attack, in civilian self defense classes you learn how to snap someone's wrist, dislocate their shoulder or throw them and break their arm with a knee.
In the classes I took years ago we were taught that the first and best option was always to run away, if that wasn't possible and you end up in a clinch then you break limbs, smash the windpipe or testicles, smash the nose and gouge the eyes,your aim is to incapacitate your assailant as quickly as possible to the extent that he can't get up and chase you again, Police don't have those options.

Lawlessness at the top of U.S society, lawlessness at the bottom, are we surprised that U.S agents torture enemy combatants?

Dear o sung wu,

Thank you for that. I have only known one policeman on a personal level. That was a sergeant in the army who was one of the most decent people I have ever known. He was a New York City cop in civilian life.

I have the impression that policemen may go through long periods without having to use weapons or physical force. Is that correct? Are there refresher courses or is the time spent in the police academy all the formal training a policeman gets unless he or she does it on his own?

It is disappointing to hear that there is not enough time spent learning unarmed techniques.

Unarmed techniques may include not only methods of physical compulsion but also psychological tactics. Is there any time spent on that sort of thing?

You mentioned the difficulties with women. Can a female policeman deal with a woman easier than a man could?
