Imagine your home gets broken into at 3AM while you're on vacation. Some shit bag uses a Buck knife to slice open a screen door, then pops open the main door using a bent screwdriver or something. A neighbor sees flashlights in your home and knows you're away so they call the cops who show up and grab the guy. One of two things can happen next.
Cops arrest the guy and charge him with B&E Night Time. It gets thrown out for some bullshit plea deal or CWOF. They get to skate while you've gotta pay for a new door or window or whatever.
-Or-
Cops arrest the guy and charge him with B&E Night Time, Possession of Burglarious Instruments, Trespassing, Unlawful Carry of a Dangerous Weapon, etc. That way, when his lawyers work their magic and some of those lesser charges get dropped, the bigger ones have a better chance of sticking. These days, criminal charges are really a bargaining process.
