What about Stadium TFR's?
If you read my post again, I was ONLY responding to the assertion that pilots don't know where the president will always be and you can't blame them for busting a VIP/Presidential TFR. There is no excuse for that, because you should be checking TFRs for hazards anyway.
As for stadium TFRs, again, I'm rather indifferent - I can see people making arguments either way. That said, playing devil's advocate to what I'm assuming your position on the subject is, when an event is occurring at a large stadium, there is usually an escalated level of traffic due to blimps, helicopters, etc. In that case, one could argue that becomes a hazard so they don't want other GA in the area. The midair collision of two new helicopters covering a Phoenix police chase years ago goes to show there is real danger with that much air traffic in one area. Again, just playing devil's advocate here.
