(CNN)Rapper 21 Savage says his nearly 10-day detention by the Immigration and Customs Enforcement agency accentuates what he says are the agency's flaws. "I don't think the policy is broken, I feel like the way they enforce the policy is broken," the rapper said in an interview with ABC's "Good Morning America." "I've been here ...19 years, this is all I know," the 26-year-old rapper said. "I don't feel like you should be arrested and put in a place where a murderer would be, for just being in the country too long."
