Idiot for the day

Slate has an article by Elliot Hannon about yet another dumb kid with gubs:

A high school student in Virginia was arrested recently for bringing a full arsenal of weapons to school. Local police were able to intercept eighteen-year-old Austin Martin after “the K9 Unit alerted on the student’s vehicle, which resulted in Middlesex Sheriff’s Office detectives recovering four loaded firearms, two of which were handguns, several knives, and over six hundred rounds of ammunition,” the Middlesex County Sheriff’s Office said in a release. Some of the ammunition didn’t fit any of the weapons in Martin’s vehicle, meaning he presumably has more guns somewhere else.
It’s a pretty terrifying haul for a kid to bring to school, no matter how they were intended to be used, and police are still investigating the incident. Martin has been charged with a felony count of bringing firearms on school property and released on $1,500 bond.

Rico says that this was, to use an ugly phrase, a bit of overkill... And why did he get out so cheap (given that the bond fee is only $150), if he might still have other gubs somewhere?
