I took you up on your dare and checked the website you cited. Nothing in the story indicates that the three young men, aged 16-19 had anything in mind other than burglary. The weapons you describe were never used. Instead three stupid teenagers were killed by another young man with a semi-automatic rifle.

I dare you to look the families of those dumb kids in the eye and tell them that their sons deserved to die for an attempted burglary.
