I think the police have over-reacted. Not all dealers have armorys in their homes.
It is much worse than that. In 1980 there were 900 SWAT Teams in this country. Now there are over 50,000. The worst abuse has been by paid criminal informants who get paid by the bust. One of the DEAs leading ones admitted to fingering dozens of innocent people who were convicted on his testimony alone.
Here is a good article about some of these abuses:
Stop Abusing Snitchin'
Two things that always happen under prohibition is corruption of the police and declining respect for the laws:
"The prestige of government has undoubtedly been lowered considerably by the prohibition law. For nothing is more destructive of respect for the government and the law of the land than passing laws which cannot be enforced. It is an open secret that the dangerous increase of crime in this country is closely connected with this."
Albert Einstein, "My First Impression of the U.S.A.", 1921
corruption of the police and declining respect for the laws: That's happening anyway. There is a general disintegration of society. Legalizing drugs won't change that. I honestly believe that this "great experiment" is nearly at an end. And I believe that the "slippery slope" hastened it. 20 years ago, Obama would have NEVER been elected. But here we are with the chief socialist firmly ensconced in the WH.
