What are the current challenges and frustrations faced by border agents regarding immigration enforcement at the U.S. border?

Border agents are experiencing unprecedented levels of frustration due to overwhelming migrant flows and current immigration policies. According to border security experts, agents are dealing with 250 to 500 migrants crossing daily, creating an unmanageable situation that has left law enforcement feeling overwhelmed and under-resourced. The situation is further complicated by powerful drug cartels who have effectively taken control of border operations. These criminal organizations use heavily reinforced vehicles called "Los Monstros" (the monsters) and exploit gaps in border enforcement to facilitate human trafficking and drug smuggling. This crisis has become a significant national security concern, with agents calling for urgent policy reforms. The combination of massive daily crossings and cartel influence has created what many describe as an "open border" situation that challenges traditional law enforcement capabilities.
