Here's a beaut.
A woman is claiming that she was harassed over her child's sippy cup while at the airport. The TSA is saying they dealt with the situation just fine and that she was the one overreacting (news link here). The TSA actually went ahead and posted the security footage of the incident (and I absolutely love that they put it in the MythBusters section).
The incident is viewable here: http://www.tsa.gov/assets/wmv/dca_incident2.wmv (It's a 45 mb file).
At one minute into playing time, you see the cup incident. Her side of the story is that she was trying to take a drink and it accidentally spilled. Their side is that she intentionally dumped it.
Around 1:02 on the video, I see a shake of the arm. Never once did the cup approach this woman's lips. I see dump, arm shake, and then her trying to storm off. If you accidentally spill a beverage, you don't shake the cup to get every last drop out.
Looks intentional to me.
