Checkpoint not checkpoints. There is only one.
The checkpoint you speak of is, thanks to Kolbe's meddling, open only part of the time. They have to shut it down all the time to comply with Kolbe's legislation. There are multiple checkpoints on the only highways leading up from the border area. If the illegals can get to I-10, they're home free. There are checkpoints on I-19, Hwy 90, Hwy 80, and more. The Border Patrol says that these checkpoints are critical to their in-depth defense. Kolbe has done what he can to undermine that defense. The checkpoints needs to stay and stay permanently until the invaders stop crossing the border. And, yes, we also need a few mobile checkpoints to keep moving around.
