Even if you support the actions by the Trump administration, honestly especially so given the assertion is the cities are dangerous, it seems reasonable as a tourist to want to avoid countries, like the US, where there are active operations by military and paramilitary forces.
EDIT to increase clarity.
They are snatching people all over the city without warrants. I would not say tourists are unlikely to encounter their operations.
The majority of illegal immigration in my location are people overstaying their student visas and they're getting sent back. Saw a former co-worker's wife was sent back, no I didn't snitch, but I don't feel sorry for someone who overstayed a student visa then worked under the table for a decade.
