[mdlug] OT - IR jamming

[Dave Arbogast]

I was just in DC with my top of the line SLR digital camera. I was in 
the right place at the right time to take photos of a motorcade entering 
the big house. I was about 12 feet from them and 16 feet from the inter 
gate as it opened. (I shot for several newspapers in the day, so you 
could say I'm not am amateur.)

OK, shoot, shoot, shoot.  Daylight, immediate response pro camera. 
What's the problem ?  This was a high raking official as the tailing 
S.S. Tahoe had the back 3 windows open and 3 armored soldiers with 
fingers on their machine guns. Yes, they gave me the evil eye for trying 
to take their photo from 4 meters, but my camera refused to take their 
photo.... it took many photos minutes before they arrived and many more 
minutes after the iron gates closed behind them.

The only explanation is IR / RF  jamming of my system. I wish I had gone 
to manual focus as I do often, but I have never held down the shutter 
release with no result.  The guys following up the rear were too cool. 
None of the other motorcades we saw that day had the heavy artillery 
exposed in the trailing SUV ready to fire.
