A motorcycle cop who wrecked while escorting the President through Dallas apparently lost control when he hit a pothole.
Officer Mike Manis was changing lanes when he hit a pothole.  The motorcycle then rotated and the officer fell off.  Manis rolled about 50 feet, and has a serious case of road rash…but will be OK.  But some wonder if they should have known about every pothole along the route.  Dallas Assistant Chief Tom Lawrence says they do the best they can.  He says they will ride the route numerous times the day before an escorted drive.
A motorcycle officer was killed in a wreck whil escorting hillary clinton through dallas in 2008.
