Was your friend tackled, shackled, thrown in prison without due diligence before being deported? Was he sent to a ln alligator Alcatraz? Was he sent to a foreign country's prison?
Not sure why you think your anecdote adds anything to the topic. Nobody is saying illegal aliens shouldn't be deported. There is a police state in effect and now Trump is threatening to deport US citizens to boot.
There's this fan fiction going on that no one is getting due process before being deported. Due process does not mean a full hearing. Oftentimes, it's just a cursory review by an immigration judge.
Everyone complaining about "no due process" is really talking about what's called "expedited removal."
Expedited removal was created in 1996 and has typically been used at the border to quickly expel those who cross illegally. Now it is being used throughout the country.
"Under the expanded expedited removal policy, undocumented immigrants anywhere in the United States, who cannot prove they have resided in the U.S. for at least two years will be subject to an expedited deportation process."
Every President has used expedited removal in the past. George Bush used it to deport anyone within two weeks of entry and within 100 miles from the border. Obama and Biden also used expedited removal and it's a big reason Obama's deportation numbers were so large.
All Trump did was expand the policy so they're using it for anywhere in the country and for anyone who came in the last two years.
Trump is also using expedited removal for people coming into immigration court and as soon as their asylum cases get dismissed, he's removing them.
So technically, what he's doing is completely legal. All this hand wringing about "no due process" is not true at all. The cursory review of the case is getting due process.
