First, this is bunk.
Second, I would be interested to be informed as to how a handgun waiting period could possibly affect crime when the purchaser already has access to one or more of his or her own firearms. With over 100 million gun owners, I would have to believe that the vast majority of those purchasing a new handgun are existing owners. Michigan points to the utter absurdity of such restrictions.
Third, if you were going to have restrictions upon exercising one Constitutional right, then I would suggest that there needs to also be a waiting period for the right to buy a newspaper or magazine, or to Surf particular sites on the Internet, or to attend a house of worship, or to write a letter to your Congressman protesting his latest set of lies, etc. What is good for the goose is good for the gander.
WRT that part of my post that said,
“Michigan points to the utter absurdity of such restrictions.”
Delete that - I have no idea how that got in there. I guess that the preview function is one’s friend.
