As stated previously the best solution to protester violence 99 times out of 100 is the use of a police officers night stick. If protesters are committing acts of violence than appropriate force is warranted. If the danger warrants it in rare cases
the use of lethal force is appropriate.
The Constitution does allow the peaceful practice of free speech. This does not include looting, arson and assault of law enforcement officers. At Kent State all three conditions existed. The problem was that those who were killed were apparently
too far back to have been the instigators. The people throwing rocks at the national
guard deserved to be shot.
The problem with government is that they are willing to use law enforcement tools against unpopular protesters. The Clinton administration did use the RICO statutes against the anti abortion movement which was largely peaceful. RICO should be used to make communist and anarchist leaders responsible for the acts of violence they sanction.
I have zero sympathy for protesters who pick a fight with cops. A few rounds with a night stick typically delivers the message. In Canada the police should be encouraged to use appropriate force if they are threatened or anarchists are looting. They also should be required to pay for their own hospitalization.
The key word here is peaceful protest. This is quite different from a riot. Peaceful
protest is part of our protected rights. If law enforcement does not act decisively
these riots may go on for days. At the time of Kent State America was fed up with the violence sparked by Communist agitators. The sentiment at the time was people who throw stones at people with guns deserve their fate.
