why is ICE involved in enforcing this?
Some of the electrons were rumored to have entered the country illegally...
The same reason ICE (not yet a totally tarnished acronym) is loaning out drones to domestic SWAT teams.
Following 9/11 America chose to exchange security for freedom. ICE, ATF, FBI, TSA, etc. all are under the umbrella of Homeland Security, /aka/ the new American gestapo.
Just like 1936, most of the worker bees don’t have a clue about the goals of the leadership. The draconian abridgment of the Constitution will be punctuated by the opportunities afforded through crisis, real or manufactured. This is indeed the new face of the Civil Army that Obozo threatened America with when he took office.
Because it's easier to do this instead of finding terrorists that want to kill us?
ICE had to find some reason to justify it’s existence since it no longer seems to be enforcing immigration laws.
Because "they" the CIS work for the alleged rights of Hollywood and not the inherent Constitutonal rights of American citizens. They'd rather find ways to enforce laws against American citizens than against those of illegal standing who steal the identity of American citizens. Hollywood is a prime supporter of illegal immigration and the anti-gun rights movement and they regularly get special enforcement attention and taxpayer subsidies while American citizens get screwed.
