Those that remember Kent State also remember that there were demonstrations and takeovers on campuses across the land, with little or no action taken against the rioters.
Things kind of stopped AFTER Kent State.
This has been going on nigh on 50 years and for the most part the ONLY time the police really reacted was against the Korean Merchants in LA who were protecting their business establishments.
Opening fire on them - the looters and rioters - may be the ONLY way to stop it but it really isn’t all that practical.
Maybe a page from Bull Connors book - Firehoses and dogs They both ‘worked’ to keep things under control.
The problem is not that one criminal was shot.
The problem is that not enough criminals have been shot.
