I agree that he should be careful about appearing to pass comment on these incidents. Obama's big mouth has inflamed these incidents.
But, even before assigning responsibility, it's fair to characterize these deaths as "tragic" and "senseless". They didn't have to happen -- the chain of events leading to them could have been broken before they occurred.
Frankly, I'm concerned about the death in MN, if the facts are correct as reported. The victim had a CHL and told the officer that he was armed. He was shot while trying to get out his ID.
We don't know what really happened. I hope the officer was wearing a body camera. But, I think it's really irresponsible to characterize this as a racial incident, as the MN governor has already done.
(An aside: Dayton is a real ass, and always has been. He ran for office multiple times before he finally managed to get in, despite his own family reportedly contributing heavily to his opponents).
CHL holders nationwide should be standing up and demanding an investigation into the shooting in MN.
