From The Joplin Globe:

Police say it has neither reduced nor increased crime overall. People don’t seem to be shooting others, or themselves, by accident in any greater numbers.

In rural Jefferson County, Sheriff Oliver “Glenn” Boyer said he hasn’t seen evidence that the concealed weapons encourage gunfights, as many critics had worried.
“I feel a lot more comfortable now that we haven’t seen the ’John Wayne syndrome’ in effect,” Boyer said.

So... can we keep our constitutional right to bear arms??? :)
