A .22 may go only a mile but it only lands in one place, just like any other rifle bullet. How dangerous is that? They hunt squirrels with .22s, don't they? Heck, more people are killed riding motorcycles than by squirrel hunters, and bike riding is still legal. Isn't it?
Crow hunting with rifles was legal before the DNR put a season on them. I don't recall any wholesale slaughter of the populace then. The shotgun-only thing has nothing to do with safety.
If you do your homework on the crow thing, you will find that the reason crows are protected is they got included with the doves, etc., because they are migratory birds and the people who drafted the agreement with Mexico failed to specifically exempt crows from the agreement.
And that, according to our lawmakers, is why Wisconsinites must eat crow.
