Last week, the Boston Police appeared before the U.S. Congress and blamed the FBI for not sharing information with them regarding tips they received two years ago from the Russian government, on one of the Boston Marathon bombers, Tamerlan Tsarnaev. 4 people died in the terrorist attack, including an 8-year-old boy and over 270 were injured. The Judiciary Report is of the belief, had Tsarnaev been detained 2-years ago when the credible tip came in from the Russian government, the attack could have been prevented. 

Currently, the FBI and its sister agency, Homeland Security, maintain a list of terrorist suspects. Many of said terrorists are of foreign origin, living in America and under current laws, eligible for deportation. I state this as an immigrant - any foreigner living in America threatening over the phone, online or in person, to wage jihad is not a model citizen. These are not Mexican, Caribbean or European immigrants coming to America in seeking a better life and increased wages, adding to the workforce. These are violent, destructive individuals hell-bent on deadly jihad against society's most vulnerable people. 

It stands to reason, threatening the life of the President of the United States, is a serious crime carrying substantial prison time - therefore, threatening jihad against scores of innocent people, should carry the same weight in court. It is a crime, but one the FBI has been negligent in pursuing, using wiretap, email and other audio evidence they have in their possession, regarding a number of jihadist in America.

The FBI is being very unwise with its list. You have to be proactive regarding the list, not reactive when something terrible happens. Learn to nip things in the bud before it becomes a terrible problem. Either you build a sufficient Supermax styled facility to house terrorists or start deporting people with said leanings (however, the latter is risky, as history has shown, they will directly link up with terrorist groups abroad). Deportation is the quick, safe solution, but it is better to detain them while one can. 

You can't have it both ways and expect everything to be alright, in maintaining a terrorist list and doing nothing about the individuals on it, running up taxpayer bills in simply watching them. Either you lock them up or send them home, but you can't leave jihadists roaming around among innocent people in society. Go over the list and do something about it.
