While I would expect the military and the police to step aside for that many vets, consider: Who has his finger on the nuke button?
Do you believe for a minute that those in Washington would hesitate to push that button if they thought there was any danger to them at all? Even if that group was in a big city like New York? I don't! And don't believe they wouldn't know if you set something up on internet. Thanks to Clinton every computer, phone, etc. in the US has a chip in it that records every message and passes it along to Washington for review. So be careful calling for something like this.
