The Arizona State Police were pursuing a vehicle which was trying to ram another vehicle off I-10. When the offender refused to stop, the troopers stopped the vehicle the hard way.
A driver on San Tan Loop 202 in Arizona called 911 saying the car behind her was chasing and rear-ending her. The suspect kept ramming the driver even after Arizona Department of Public Safety troopers showed up, so they decided to deploy a Grappler Bumper to end the pursuit.
The Grappler Bumper is a net that’s attached to the front of a police vehicle and can be lowered with the touch of a button. When the net contacts the tire, it’s pulled over the axel and the vehicle is immobilized within five or six seconds.
I’m not sure that would work as well on clustered city streets, but it sure works on highways. You can see the video of the incident below the fold. It’s pretty impressive.
