Why is the mass media silent about police spying on muslims?

A series of articles by The Associated Press has exposed constitutionally suspect surveillance of Muslims in New York, New Jersey, Long Island and beyond. Unearthed police records noticeably lack any apparent link to suspected criminal activity, or any obvious payoff for public safety.       

In particular, the A.P. reports revealed widespread police spying and the creation of police records containing information on Muslim people, mosques and campus groups, as well as luncheonettes, dollar stores and other legitimate businesses owned and frequented by Muslims, with no apparent reason to think anything wrong was going on.
  
It is a distressing fact of life that mistreatment of Muslims does not draw nearly the protest that it should. But not just Muslims are threatened by this seemingly excessive warrantless surveillance and record-keeping. Today Muslims are the target. In the past it was protesters against the Vietnam War, civil rights activists, socialists. Tomorrow it will be another vulnerable group whose lawful behavior is blended into criminal activity. 
The New York Police Department collected information on businesses owned by second- and third-generation Americans specifically because they were Muslims, according to newly obtained secret documents. They show in the clearest terms yet that police were monitoring people based on religion, despite claims from Mayor Michael Bloomberg to the contrary.

The NYPD has faced intense criticism from Muslims, lawmakers - and even the FBI - for widespread spying operations that put entire neighborhoods under surveillance. Police put the names of innocent people in secret files and monitored the mosques, student groups and businesses that make up the Muslim landscape of the northeastern U.S.http://www.nytimes.com/2012/03/04/opinion/sunday/surveillance-security-and-civil-liberties.html?_r=1&ref=opinion
