I understand the case you are trying to make, but Mr. Garner is responsible for Mr. Garner's death. He was overweight, asthmatic, diabetic, and decided to fight the police. All he had to do was sick his wrists out and take the cuffs and do his arguing in court. He didn't die at the scene, but at the hospital from asthma. I'm sure the attack was from the arrest, but why get all upset at the scene?
Police are just a tool law enforcement uses to bring suspects under control. Fighting and resisting Police is always a futile thing. They won't just back off and say "Well this guy doesn't want to go with us, so lets just leave him alone". They will bring in 15 more officers if necessary to get the job done, but get it done, they will. People don't get shot just sitting in their vehicle saying yes sir and no sir.
The case for taxes on cigs is for legislators, not for the police. The police take oaths to enforce said laws.
