I agree the concept of preemptive wars is really frightening. That goes counter to the concept that you have to actually run a red light before you get a ticket for running a red light. There is nothing wrong with having a cop watching and prepared to write that ticket, but the ticket should not be given until the light is run. There is nothing wrong with having a military ready that can fight a war, but I think there is something wrong with starting the war. Maybe that is why conspiracy is really hard to prove in court. That becomes a bit of a murky, preemptive action, proving conspiracy. I do like the idea of a cop visibly sitting at a corner where people often run red lights as a deterent, but don't write the ticket until the light is run.
I agree you almost always follow the money, but I do not believe the war on drugs originated just to populate the jails. But then I don't use drugs. I did not like how grass took away my self-control. I can face life using my unaltered mind. I don't even like pain-killers, even aspirin, unless there is a real strong need. If you want to stop the war on drugs, stop using drugs. Prison populations drop, the Mexican drug cartels lose their power, the Taliban loses a major source of funding. But as long as you use drugs, you are funding those efforts. Have a nice day and follow the money.
