Parent allows child to pull signs out of yard

So, for the last month or so someone has been yanking out our John Bambenek sign and our Ron Paul sign and throwing them on the ground in our yard. Not the end of the world, but a bit annoying. So we set up two security cameras and whoever it was stopped this juvenile behavior for a couple weeks but they struck again this afternoon. This whole time we thought the culprit was a

stupid teenage boy but it turns out that it's a little boy, probably 7 or 8 WITH HIS MOTHER. Seriously?!?! The boy comes right up in our yard and without even pausing yanks up the sign and throws it on the ground. He goes to the other sign, looking back at his mom for approval and yanks that sign up as well. And she just keeps walking like nothing happened. I would just like to know how a person gets to the point where they don't even bat an eye while their son continues FOR A MONTH to trespass into someone's yard and yank down a couple signs.  I have to assume the parent actually encourages this behavior.  What is wrong with people? Now my wife and I are cooking up some creative ideas to deter this behavior in the future.
