So. This decent looking college gal comes up in your house and strips while bouncing on the bed, and there is no video!
Damn Obama phones!
Since you love lawyers, here are some reasons that the "victim" was absolutely correct in calling 5-0:
1) If the girl was intoxicated, she couldn't "consent" to the photography. A video voyeurism charge comes with some nasty baggage.
2) Had she passed out, she could misremember the events that landed her in that particular apartment and cried foul. A rape charge, regardless of outcome, comes with some nasty baggage.
Bottom line: intoxicated strangers exhibiting bizarre behavior are best avoided altogether, but if they invade your space you should call in a third party and begin the CYA phase of the plan.
