Well considering the administration has repeatedly called Alex Pretti and Renee Nicole Good "TERRORISTS", I would consider "1400 ISIS terrorists" a highly dubious statistic, in fact in a brief search for a reputable source of your claim of "1400 ISIS terrorists" I've not found any source for that, link???

You ask "Is, say, 1 in 100 people coming in being a criminal OK?"

Well considering that about 1.4% of the overall population is current incarcerated in our "Land of the Free", yeah 1 in 100 would be an improvement!

People are against ICE in growing numbers because of their tactics of run around hide their identities like bandits and gestapo thugs. Their ignoring of court orders, constant lies, constant blatant violations of the 1st, 2nd, 4th amendments constantly, and violations of rights of people such as immigrants following the processes of asylum, several citizens that have been arrested wrongly, and the terrible tortuous treatment an the joy and pride this corrupt disgusting administration takes in being cruel to people!
