This is undoubtedly the work of someone with an Assault Dremel. I'll bet that it even had a comfortable grip-thingy and a high-capacity motor. We should require licensing and registration of Assault Dremels, and do background checks on anyone who wants to buy one. Who needs an Assault Dremel, really?
Any time, Constantine.
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
