Lyric discussion by rust in peace 

Cover art for Have Cool, Will Travel lyrics by Megadeth

It's about school shootings. Mothers pack their kids lunches thinking it will be a normal day but it isn't going to be. After the killings are done the media wonder why it happened.

We the people, point our fingers, blame and wonder why.

Things like this are concluded by video games and violence on tv.

There's no recess and no rules in the school of life.

Best lyrics in this whole song. This tells us to expect anything to happen.
