Correct, whoever made the decision to create ICE, as it became a security risk that lead to deaths. Glad that's what you said, and no other valid interpretation.
While there were deaths, I didn't see any that were the result of a "security risk". I did see a whole lot of stupid people doing stupid things, and none of them were ICE agents, so I'm surprised there weren't more deaths.
Random masked goons in unmarked cars trying to arrest people is pretty damn stupid, yes. Same goons putting themselves in front of cars, and shooting through side windows of cars driving away, or shooting at random people on the street, is pretty damn stupid.
The ICE agent was 100% in the wrong, completely, totally unjustified in murdering Renee Good.
Nothing you wrote changes that.
It's actually a relatively new agency and clearly not effective.
Also, the abuses and violence are staggering. And they managed to deport or mistreat actual citizens, because they did not cared. Again, not effective.
Here is the problem - conservative and right wing people use "effective" as euphemism for "we want to see as much cruelty and abuse as possible".
1. Have an enforcement agency going around killing people, and locking people up who have valid reason to exist in country waiting for status updates.
OR
2. Complete anarchy and chaos, monkeys flying planes, elephants driving taxis, dogs marrying cats.
Actually you know what, I reckon give the elephants a go.
