they are following orders from the commander in chief that has them "babysitting" the border. I agree that their job is to technically follow the order of cheeto in chief and protect our country from enemies but this ain't it fam. I'm from Laredo and walked across the bridge the last time I came back from Monterrey (less than a month ago). there is no shortage of CBP officers. the military can help organize the passage and asylum process, but you're being ignorant if you believe they weren't sent for theatrics. the correct way to seek asylum is to present yourself at a port of entry (which is what they're doing/going to do) and the process begins.
As to the migrants now being in Mexico and therefore their asylum now being invalid because they are "safe" in Mexico is moot. The statute allows for a foreign national to present themselves at our border and we ultimately decide if their reasons for seeking asylum in the US have merit. We have a specific budget for this shit (which by the way this little stunt with sending the military has exceeded or is coming close to that total amount allotted). We have done this for years but only now in recent years all of a sudden everybody is freaking out.
It is not assumed you dipshit, it is requested. like stated above we have a protocol already set out for this and will handle it accordingly. There are camps already in place in Laredo (one is on Saunders/Loop 20 if you find a map) where they are taken while this processes. if you think the CBP are incapable of handling it thats a completely separate issue and is on the gov't. to fix.
