Pick a blue or green state and tell us which state the crime rate has gone up as a result of a CCW law.
Reality wise if this law is passed, anyone walking around Washington D.C., Chicago, New York or Boston with a concealed weapon will find the cops aren't interested in an out of state license. The cops in those states will take their sweet time in verifying the license is a good one. If you're still alive.
And history ought to regard those first few casualties as CCW martyrs.
This sort of thing is exactly why I like Allen for President in 08.
