I have long renounced my f da popo sentiment; i'll opt to fight my own battle upon a break in or on the street, but if i catch a bullet(they fly around often in my neighborhood as of lately), 911 it is. I've been arrested once for a frustratingly retarded infraction (walking between train cars through the door) but the cops that dragged me farther from my destination towards that pissy, dirty cell were fine. The lady cop was nice enough to buy me skittles and soda when we got to bookings. Still hated them for conducting a secret sting operation by following me through the door into the other train car then standing around pretending their not going to arrest me.
That being said, police are not your friends, period. Some are cool peeps within themselves, but their primary objective as officers is to uphold the laws imposed by the state/Government; 95% of which go against the common citizen's financial and individual interests/ freedoms, and they'll uphold whatever for that paycheck. Others don't give a damn about upholding anything or jelping people and are glad to legally whoop ass, shoot guns at live targets, and hold federally sanctioned authority over others for the base thrill of it. Coupled with the fact that a growing number of police in the last few years are generally more inclined towards beating and shooting people/dogs with little to no requirement or provocation, then the officer and the brass taking all necessary steps to lie, cover-up and justify said violent acts further shows us that the cops are not here to help us.
The man here was recording the scene, which is not illegal. That doesn't stop police from becoming angry and arresting the person recording anyway. Granted, this man was a bit obnoxious, and should have recorded at a safer distance, far from the cops, but observing how both cops forcefully and unnecessarily grabbed and contorted the man's arms despite his compliance, and the countless cases of cops angrily pursuing anyone recording them doing something they shouldn't be doing (beating, shooting dudes for little to no reason), then it's safe to assume these cops were not interested in securing the scene and keeping everyone safe. Also remember that they LIE, and sometimes switches it up upon the surfacing of damning video evidence. So the reason of them trying to keep a crime scene secure, keep people safe and turn down his music is according to the police.
I would say that although the rot did look like he was jumping at the cop, i think i single bullet or a tazer would have been sufficient enough, then quickly back away and let the owner calm Mr. Rot down. Instead we have 4 bullets, and the cop still in his combat stance pointing his glock at a dog that is OBVIOUSLY no longer a danger to anyone(his body is too busy spazzing on it's side from being shot 4 times). I'm gonna say cops fault here; i'll recognize and admit if it isn't.
I think the government purposefully have police departments fill their ranks with people lacking a moral compass; those who are willing to commit violence when not needed or enforce insane laws, and those who care not what goes on as long as they get paid. Cops are not your friend people.
