A number of 173 home invasions in a city the size of Tucson sure seems more significant than some who propose that if you aren't in the drug trade you have nothing to worry about. Even in 3/4 are tied to the drug trade, that leaves 44 home invasions in Tucson for reasons other than drugs.
Besides, even though we/I give LEOs a hard time for screwing up the addy on warrants, I doubt drug/gun/cash-seeking home invaders would do any better. IOW, just becasue you are not into drugs does not mean that home invaders won't confuse you with the meth-cookers down the street.
