They don’t seriously enforce laws against illegal immigration, so this is the only part they care about:
“(5) to make arrests-
(A) for any offense against the United States, if the offense is committed in the officer’s or employee’s presence, or
(B) for any felony cognizable under the laws of the United States, if the officer or employee has reasonable grounds to believe that the person to be arrested has committed or is committing such a felony, if the officer or employee is performing duties relating to the enforcement of the immigration laws at the time of the arrest and if there is a likelihood of the person escaping before a warrant can be obtained for his arrest.”
Just a “legal” way to stop and search anyone without probable cause.
Actually, the Border Patrol Agents do care and are working harder than you realize to stop, catch, deport/jail illegals/drug smugglers and while doing so they face a very dangerous environment, from the terrain to the MEXICAN ARMY, the Agents are undeterred in their efforts.
It is better to direct your comment to the DHS “leadership” and The One, not the Agent in the field when it comes to immigration policy.
