Everyone knows the only thing people do with their cell phones is take weird sex pictures. When moms saw a man lurking around San Francisco's Mountain Lake Park apparently taking cell phone pics of their kids, they leaped into action.

Here's the email that was passed among parents' lists earlier this month, warning of the man in the PT Cruiser: Please help spread the word to people you know in this neighborhood. I have seen this man 2 times at the lower playground at MLP. He does NOT have children and pretends like he does and is there to do pull ups. He takes pictures of the kids with his phone. He drives a silver PT cruiser and wears sunglasses. He takes pictures of BOTH boys and girls. He looks for kids that don't have care givers near by. I have not confronted him, but take Scout and stand next to him. He gets nervous and puts his phone away and eventually leaves. I personally believe that given the chance he might engage the kids and who knows what could happen.... Gawker
