I can't say I've ever been to classes that have that issue or have heard anyone with a similar complaint.
If it's really that much of a problem for your specific school, class, or just you (for some reason), then it can easily be remedied with a power strip, or several if that's really how bad it is.
I'm reluctant to take your word at face value, though. Lots of hyperbole going on on these forums.
Badges and "identification" can be bought at dollar stores.
Nobody is going to be able to check their authenticity in the middle of a firefight, and by the time you let criminals enter your house to show you their "ID", it's already too late.
