1. The pols didn't - the people did
2. The crazies have always been high, the only thing that changed was that it's legal
3. Show me the toxicology reports - I'd be willing to wager there was more in the perp's system than MJ - until the facts are released, it's only claims.
One of the problems is the pot is much stronger than when we had in the 60s and 70s. They are trying to get emergency legislation to control edibles. Many BUT NOT ALL of the same idiots who want guns locked up to savvvvvve the children dont want similar laws for edibles. Common sense is not common. All responsible gun owners secure their weapons around children and most edible pot folks would do the same. You cant legislate to fix stupidity.
