Rapper Ice-T defended a lyric change from his 1992 song "Cop Killer" to "ICE Killer" during a Los Angeles concert last year, saying Wednesday it was meant as a protest against federal immigration enforcement. Ice-T called the switch to "ICE Killer" a form of protest but warned that any violence against federal agents could escalate tensions across the country. "’ICE Killer,’ ‘Cop Killer,’ it's really protest. Tensions with ICE flared earlier this month following the death of Renee Nicole Good during a federal enforcement action in Minneapolis. The shooting sparked weeks of intense protests in the city.
