I'm not sure exactly what kind of armored vehicles ICE has. I'm pretty sure some of them would qualify as tanks at least in WW1. The war to end all wars... if only.
There are actually valid reasons for BORTAC to be armed to the gills, but they're meant to point all that firepower at organized crime (cartels) in the border zone, not Americans in Chicago.
But fair argument - words matter. I was being glib with "tanks". What I really mean is that anyone backed by the power of the US government to extrajudiciously kidnap people and deport them without due process is not a vulnerable group (by definition) and should not be a protected class (in my opinion).
Except there were no shotguns in the Trojan Wars, and there were tanks in WW1, many less armed and armoured than today's IFVs/APCs.
Regardless, the parent poster was right - I cannot find any proof of ICE having modern tanks, just some lighter equipment. And regardless of that, I think my point stands - ICE is emphatically not a vulnerable group, and Google is saying they are because they want Most Favored Company status with our increasingly fascist regime.
