I think it's wrong to overreact to what Trump is doing and label things you don't like as "lacking due process" because when he does do something illegal you'll be like the boy who cried wolf.
Trump is following the law on immigration but many people think otherwise because of media misinformation. Take the case of Kilmar Abrego Garcia. He had his due process and a judge ordered his removal in 2019. He also received "withholding of removal" from being sent home to El Salvador. The administration made a mistake in deporting him there, but they are ordered to deport him.
Many of the people you see in the news also had their day in court.
But media is also spreading misinformation on arrests. ICE doesn't need warrants to arrest people. This has always been the case. They can also arrest anyone (citizen or not) who commits an illegal act in their presence.
It's okay to not like what Trump is doing, but you should protest to change the law, not deny reality.
Also, I'm surprised you're using "illegal" instead of "undocumented".
