I'm not sure what state you're living in, but in most states in which I'm familiar, that too would be violation of law.
In most states (probably all states), you can't videotape - and maybe can't audio record - somewhere where they have a clear expectation of privacy. A "changing room" or bathroom presents a clear expectation of privacy.P> In this case, it's a little more complicated. Because of the advent and subsequent ubiquity of security cameras, you may be videotaped virtually anywhere that doesn't have a reasonable expectation of privacy, which is effectively anyplace that isn't bathroom or changing room or someplace similar. So, these journalists aren't in jeopardy for the videotaping, per se.
The audio portion of that tape, however, presents a different set of problems. From reading the MD law (§ 10-402), and the court rulings associated with that law, it's clear that these kids have some potential problems on their hands if, after reviewing the complaint, the prosecutor decides to move forward with the case. I'm HIGHLY doubtful that a prosecutor would abuse his discretion in a case involving these circumstances. I just don't think this is moving forward to prosecution, irrespective of ACORN's or their employee's protestations.
I have read that in MD, a plaintiff can prevail in a civil case ONLY if he can demonstrate that the defendant(s) knew the taping to be illegal.
I cant imagine that Hannah or James knew about the law. Neither lives in MD, and both were kids when Linda Tripp had her troubles.
No disrespect meant, but I would guess you're not very familiar with Patricia Jessamy's track record. No prosecutor with brains and integrity would pursue this, but that statement excludes Ms Jessamy.
