Those dumb ****s threw shit at people with weapons. And continued to do it after apparently being told to stop. The end result could have been predicted.
It was not just "people with weapons". It was mostly scared young men between 18 and 22 years old who had joined the NG to avoid serving in VN themselves,and they were'nt at Ohio State because they wanted to be,or because they wanted to shoot hippies.
And,as usual,the left manipulated the naive into going into the front lines were THEY would be the ones to take the brunt of any reprisals,while they remained far in the background where THEY were safe.
The left WANTED this to happen and engineered it. Remember,these NG guys were scared kids themselves,and they didn't really understand why they were being verbally and physically attacked by people their age. ALL it takes in a situation like that for very bad things to happen is for ONE firearm to fire. It could even fire accidentally and the outcome would be no different,the other people with guns would think THEY were the ones being shot at because they knew that THEY had not shot anyone,so they open fire.
There are two absolute truths you can take from this. The first is that the left WANTED innocent kids to be killed in order to advance their agenda,and the second thing being that one shot leads to a chain reaction.
