VIP TFRs are never warranted. The people who are thought to be very important in western democratic governments never really are. History suggests a different view:
When FDR died in office during the largest war in modern history, did it affect the security of the U.S. in any measurable way?
When Kennedy was killed during the cold war, did it affect the security of the U.S. in any measurable way?
Except for the abruptness and terrible human loss, is there any difference to the security of the U.S. whether a president is removed from office by death or by losing a reelection?
The Secret Service should be made to perform its security functions within the confines of the rule that every citizen going about their lawful business has an equal right to public commons, and that the president is just another citizen within that commons.
Of course I know that it would easier to move a mountain than to see any of what I wrote ever become remotely close to reality.
By your comments you suggest that the President isn't important, almost a figure head? He can easily be replaced. Well I won't go into politics but not enacting security measures for VIPs will never happen. .
Example: I flew Gen McChrystal around in Afghanistan. Everywhere he went he rolled in heavy with security. The argument would be, well a common soldier doesn't have this protection why does he? Problem is he isn't as easy to replace as a common soldier. This is why the POTUS had such a dilemma when replacing him. That person has built a foundation and only they have innate knowledge of the situation. Once again if you believe the President can easily be replaced or that his asassination would have no effect on the psyche of the American people or those who protect him, so be it. Your opinion.
As Three Finger Jack brought up earlier this is nothing more than people complaining because it affects their precious freedoms. Is a TFR really affecting our freedoms that much that I can't wait a day out of 365 of not flying. If a flight school can't wait a day or two of not flying because they'll possibly fold well then I'd say they were on the way to bankruptcy long before that TFR came. When it comes down to it it's all about us being willing to sacrifice a little freedom for a common good.
I'd like to bring up a couple cases of the American public who can't sacrifice a little of their freedom for a common good. In my field of helicopter EMS we had a particular cardiac hospital that we dropped patients off at. Well the public not wanting to be inconvienced by the noise of a helicopter landing maybe once a week got that pad shut down. Now we have to land at an airport miles away and off load the patient onto the ambulance. All of this affecting the care (safety) of that patient.
Here's another one. Anyone who's lived in central Georgia for an extended period of time has heard sonic booms from the boys at Warner Robbins doing post maint test flights. Even though they're busting the number at close to 50,000 ft, it's still quite loud on the ground. The thing was these flights were occurring maybe once a week. With that one boom once a week the locals had enough pull to convince the local leaders to have the F-15s fly all the way out to sea to do that particular check on the card. a complete waste of fuel and money because people didn't want to be inconvienced. Today I'm not even sure if they do any supersonic stuff over central GA. I won't even go into the complaints I've seen because of MTRs affecting the publics freedom.
What I'm getting at is if we expect the public to deal with aviation every now and then, than why can't we deal with the public affecting aviation every now and then?
Finally, to say that a TFR hasn't been effective in early warning of an airborne threat is a pure assumption. Also who knows what a C-172 packed with explosives would do. I have seen a 12 inch strip of C-4 blow the heck out of a van! Yes the dimensions are extreme, there's no denying that but AOPA is fighting that right now. All I'm saying is until then I think we can be a little more understanding of the current dimensions.
