I'll see your $1000 and raise you $5 million. The guy goes and smokes some pot at a party and the government comes in, locks him up in a hole, and forgets about him? This isn't the way I want my government to operate.
Maybe you don't think its a big deal because he was at a bust. But, in other countries, police abuse has had a way of escalating. How'd you like something like that to happen to you over something other than drugs... maybe a weapons charge (wrong size magazine in a restrictive state)... maybe a minor fight?
Some people need to go to jail for this.
