The threats stem from a YouTube video showing a tense confrontation between that deputy and a gun rights activist.
On the video a man armed with a holstered handgun is seen outside the Oakland County Sheriff' Office's maximum security correctional facility.
He's outside the jail with a video camera when he's approached by a deputy, who alleged that the man was recording video of employee cars. The deputy asks for ID, but the man says he has no legal responsibility to give his name.
Eventually, the deputy pulls ID from the man's pocket. He returned it and the man was allowed to leave, but later the video showed up on YouTube with the headline "Rights blatantly violated for filming the police."
FOX 2 has learned the man who shot the video is Shawn Nixon. Nixon, 39, has been featured in a cable TV documentary. He's also the central figure in a video where he carried a rifle outside Lamphere High school in Madison Heights.
FOX 2 tried to talk with Nixon for this story but his neighbors at his Royal Oak apartment say he moved out two weeks ago with an eviction notice on his apartment door.
Now the video from outside the jail in Pontiac posted on YouTube has brought death threats aimed at Oakland County Deputies according to the Sheriff.
An investigation has been launched to see who is making the threats. Police believe that Nixon is not making the threats, but rather
Rick Ector a Detroit firearm instructor who teaches classes for gun owner permits saw the video.
"What really bothers me about this is that the people who find his conduct admirable that stooped to making death threats to the officer," he said. "I really have a huge problem with it."
Ector says he views Nixon's behavior both outside the jail and outside the high school as disgusting.
"He seems to be an attention hound who wants to milk media coverage and confrontation with law enforcement and put it on YouTube," he said. "Law-abiding citizens who carry guns everyday don't seek out confrontation with law enforcement. We are all united."
Investigators believe Nixon is wrong, but think that the threats are coming from those reacting to the video.
Nixon could be charged with trespassing, but he was not arrested at the scene.
Investigators say they had to investigate Nixon because the federal government has been warning about credible threats made toward police, fire and military installations.
