Enlighten me on ICE?

I’m genuinely not understanding the uproar about ICE. Someone explain? Every country has immigration policies. I’m not saying our deportation history has gold stars but if someone came into the country illegally, established or not, there are consequences. There is due process. Even the most wanderlust countries have stricter policies than America. So why is it wrong that America does it? Shouldn’t citizens be vetted?

I can’t expect to go to Italy for an extended period of time, decide I love it, find a job, make a living, and then be surprised when I’m getting kicked out because I didn’t follow the rules. It doesn’t make sense.

Edit to add: definitely agreeing on improving our immigration process and having more resources available. Everyone deserves a fair, sanitary, efficient, safe process!

Thanks for your input!
