After the newer border wall was built, it reduced crossings in those areas by >70%.
Of course, when the current policy amounts to 'we won't stop you when you come in', it not only doesn't deter crossings but it encourages them.
It's ironic, because it reflects the shifting landscape of Democrat policy, who's members repeatedly voted for a border wall and border security measures (Biden voted for the 2006 Secure Fence Act and has previously stated employers who employ illegals should be jailed).
Then there is the matter of the doors in the border wall being welded open by US Border Patrol. https://nypost.com/2023/08/22/border-patrol-admits-its-respo...
There are several more crossings I know of where illegals can walk around the end of the existing wall and line up to be apprehended then released to NGOs. They line up and wait in a line to be taken by US Border Patrol buses at night.
