There is widespread evidence of reactionary measures being taken by the enforcers of the One Percent against even the reporting and documenting by journalists or ordinary citizens of police brutality and other illegal activities.
Police harassing citizens lawfully documenting police activities taking place in public is a "widespread and continuing" problem according to the ACLU.Also, see this audio report and transcript of a photojournalist from Santa Cruz, California, who is being charges with several felonies for simply covering a protest event in that city. See this regarding widespread arrests of journalists in New York during recent protests.
"The right of citizens to record the police is a critical check and balance," an ACLU analyst noted during a September 2011 speech where he referenced six incidents in five cities of police arresting citizen photographers during just the spring of last year.
Yes, police attacking civilians for lawfully photographing public spaces, police routinely employing unlawful excessive force and prosecutors too frequently turning a blind eye to such police misconduct are all nationwide problems.
