They arrested Kelly on charges of violating an
outdated Pennsylvania wiretapping law that forbids audio recordings of
any second party without their permission. In this case, that party was
the police officer.

Kelly was charged with a
felony, spent 26 hours in jail, and faces up to 10 years in prison. All
for merely recording a police officer, a public servant, while he was
on the job.

Last year, Massachusetts Attorney General Tom Reilly
threatened Internet activist Mary T. Jean with arrest and felony
prosecution for posting a video to her website of state police swarming
a home and arresting a man without a warrant.

…

Michael Gannon
of New Hampshire was also arrested on felony wiretapping charges last
year after recording a police officer who was being verbally abusive on
his
doorstep.

Photojournalist Carlos Miller was arrested in February of this year after taking pictures of on-duty police officers in Miami.

…

Philadelphia student Neftaly Cruz was arrested last year after he took pictures of a drug bust with his cell phone.

While certainly not justified, perhaps we can understand why they don’t like being filmed in an unscripted and controlled manner.

Consider Eugene Siler.
In 2005, the Campbell County, Tenn., man was confronted by five
sheriff’s deputies who (they say) suspected him of drug activity.
Siler’s wife surreptitiously switched on a tape recorder when the
police officers came inside. Over the next hour, Siler was mercilessly
beaten and tortured by the officers, who were demanding he confess to
drug activity.

Earlier this year, Iraq war veteran Elio Carrion
was shot three times at near-point-blank range by San Bernardino,
Calif., deputy Ivory Webb. Carrion was lying on the ground and was
unarmed. Video of the arrest and shooting, however, was captured by bystander Jose Louis Valdez.

Let "freedom" ring.
