A lot. Do you really believe those Nicaraguan "officers" received the same training that a typical U.S. LEO receives regardless of agency location? Puhleese! And did you notice that the "officers" formed a circle around the perp so that when they finally started shooting, other "officers" were in the line of fire? Yep, these boys were really well-trained.
It clearly demonstrates that police who hesitate to fire on suspects brandishing knives are likely to end up dead. Google the 21 foot rule if you wish to be informed.
I did. It appears the "21 foot rule" applies to an officer facing a knife-wielding subject when the officer's GUN IS HOLSTERED. Let me repeat that for you. The "21 foot rule" applies to a situation where an officer is facing a knife-wielding subject when the officer's GUN IS HOLSTERED!
That is not the situation here: Multiple LEOs, armed with both lethal and non-lethal force trained on the perp and a police dog to boot.
So who is uninformed?
The dead sociopath was only about 10 feet from the officers and was at the top of a berm. He could have closed that ground very quickly and to avoid that the officers could not afford to hesitate to shoot.
He also easily could have taken a few steps over the top of the hill pulled a concealed gun and killed officers.
If you don’t want to be shot by the cops don’t threaten to murder them and resist arrest while brandishing knives.
You sound just like Reverend Al. Do you so think Michael Brown had his hands up and Tawanna Brawley was raped?
