I'm the Canadian who was detained by ICE for two weeks

If the objective is to scare people off from going to the USA, then they're doing a magnificent job. I've heard other cases of people with green cards being arrested and put in terrible conditions, with absolutely no reason given. This woman was ready to go back home and not enter the US, but instead she was dragged through hell and only released because she was Canadian. All those with different passports get subjected to their own more oppressive and never ending hells, like being deported to a prison camp in Ecuador with no idea when you'd ever be released.

New America is absolutely terrifying.

I wonder why agents in the field, customs, immigration etc, seem so eager to implement these changes.

I'm not a psychologist, but I'm pretty sure all police forces should have very strong and active civilian oversight, because they seem to attract (or maybe even nurture) some very aggressive people.

In my country, some police forces have skulls on their uniforms and vehicles. How twisted is that?
