Princess Diana died because her driver was drunk and speeding, did you miss that? Children cry whether or not they are crowded. Photographers have the right to photograph anything visible in public as long as they have the legal right to be there, i.e. they may be barred from an active crime scene, but certainly not from a public airport. It's nice to know you oppose the Constitution, which guarantees the right to peaceably assemble. I'm not surprised you support violent actions in response to harmless activities, you seem like a very violent person.
