This was a conversation on twitter.
I was not involved , but it was published.I removed the names to make anonymous the conversation , perhaps this made the conversation unclear also . This exchange is between three persons.
First tweet is about how frustrating and angering it is to fly commercial aircraft these days. This could be causing more violence than it is.
Second tweet is about aircraft being an almost gun free zone.People are not committing violent acts because they are empty handed.
Third tweet is about People have always been able to commit violence barehanded , but on an aircraft it is hard to get away with such a crime.
