Police Brutality and The War On Drugs

In the good old U.S.A. where the people are good and moral, and where the police offer protection, this is what really happens. This shows the other side, where the police don't protect us, where they harm us.
Police in a drug raid killed Lloyd Smalley and Lillian Weiss. The police threw a flash grenade into their apartment. To make matters worse though, these people didn't have any drugs. It was a botched drug raid.
In New York City police officers chased a marijuana dealer through a schoolyard in Brooklyn. Yes, a schoolyard, leaving three children wounded. The heroic police officers then drew their guns and arrested the man, while they were still in the schoolyard and the children were still outside.
In London, police officers raided the wrong apartment and killed the tenant's dog. An informant had specifically stated that the suspect did not live in that apartment. A person's dog was killed, her apartment was raided even though it wasn't supposed to be, and the police wouldn't even apologize.
In Houston Texas, Pedro Oregon Navarro was shot twelve times by six police officers in yet another botched drug raid. The police barged into his house in the middle of the night while he was asleep. A drunken informant, on probation for a previous drug offence, told police that Navarro was a drug dealer. The police never bothered to verify this information or to get a search warrant. When they came into Navarro's house, he grabbed his gun, and was killed even though he hadn't fired once.
In Oklahoma a paraplegic in a wheelchair is serving a ten-year prison sentence for having two ounces of marijuana. Yes, two ounces. Leroy Stubblefield, a fifty-two year old quadriplegic had a license to grow marijuana for personal use. Federal agents seized his plants, which is overstepping Oregon law. These people were most likely huge threats to their communities, right?
In Wisconsin, an unarmed man was shot to death for having one ounce of marijuana. One ounce of marijuana was enough to justify shooting an unarmed man to death, in front of his seven-year-old son. Police officers really are the good guys aren't they?
This is actually considered justice? Would someone like to tell me how these drug raids are helping people?
