I guess you don't know stuff about civil asset forfeiture.
that has literally nothing to do with civil asset forfeiture. contraband aren't assets, they're evidence. all of the assets seized either go to the department of justice or stay at the precinct and are given out to cops or some stuff. None of those assets ever factor into the federal revenue. Unless, like, it gets sold, in which the federal government would get a sales tax and thats it. Even if you sold millions of dollars worth of kingpin assets the federal government would only be getting like $60,000 dollars out of that, and thats provided that all of the assets are sold in the first place
the wall is being paid for by our tax money, not mexico, or drug kingpins.
