That's substantially different from generic office tech where ICE happen to be one of millions of users.
I'm a stranger on the internet, if you don't already think that the USA's immigration raids and camps are a bad thing, I'm probably not going to be the one to convince you otherwise.
There's a lot of good journalism and commentary on the topic, so if you want to have your mind changed, do a web search and read from people much smarter and more knowledgable than me.
