There doesn't seem to be a rational explanation beyond these people are contaminated. They can't even be honest about why these thugs are killed, as though we're supposed to allow them to control our streets and responsibility is subjective.
The moment you refer to the victims of police violence as "thugs" you show the reason why there are are protests across the USA. The "thugs" you speak of are the ones wearing blue uniforms and hiding behind their "qualified immunity" shields to kill over 1500 citizens every year. These are people who have not even been charged with crimes, much less convicted, but the NAZI fringe labels them as "thugs" to justify these abuses.
Trayvon Martin was a thug. Michael Brown was a thug. The Minneapolis druggie was a thug. You're not dealing with reality.
The standard "thugification" of every black male murdered by white people, especially white police. Republicans are ignoring the looting of the public treasury by the Trump Administration and their billionaire friends, but the loot of stores must end.
Trayvon Martin was an unarmed 17 year old high school boy on his way home from the corner store with an iced tea and a bag of Skittles. Yet he ended up dead at the end of a vigilante's gun. He had never been charged with a crime, and his father was well off enough to live in a gated community. By the time the right wing media got through with Trayvon, he was a burly gang banger with a grill, who nearly killed that waste of skin, George Zimmerman, who has done nothing but prove that he should be have jailed the first time.
Michael Brown was an unarmed high school kid who stole a chocolate bar, and ended up dead at the end of a police officer's gun. He was a good student, no previous trouble with the law, and yet he's one more in a long sad string of young black men who die every year because cops' first reaction to back talk by black males is to shoot them.
