Subject: Re: Trump's fascist tilt
"The walls" built during Trump's term are relatively easily chopped, tunneled, scaled. Trumpenwall was cut some 3000 times by 2022. I'm sure Ryobi, DeWalt, Milwaukee power tool vendors love the additional sales.
Hard ladders and rope ladders are also common. And then there are the plane and boat immigrants.
If the purpose you describe is to funnel the flow for apprehension, processing, just designate areas, we already have that.
Most immigrants would be thrilled to have such an orderly opportunity. Of course, we'd need the additional staffing such as that in the bill Trump just had his cult shoot down.
