I’ll bring a camera. It is easy to separate the hard-working Americans from the leftist scum.
Not all the time it isn't. There are hard-core lefties that 'look' conservative in their appearance, and there are 'kick your butt' patriots who appear 'ragged' in their appearance, including many who served this country honorably. Not every guy with a gray ponytail and jeans is a lefty. The infiltrators will probably try to look more like average conservatives.
