I found this after watching the OPs video.

Pretty good explanation of "semi-auto" and "fully automatic" and "assault rifle" myths.
I believe that officer got into trouble for creating that video.
I believe it conflicted with the San Jose Police Department's official position at the time, and presenting himself as an officer of that department giving such information was not appreciated.
Official positions of many departments (decided by the Brass and politicians, so essentialy the positions of a department are the positions of the politicians) is for gun control, even if individual officers feel differently.
Of course that likely comes from people voting for the most authoritarian figures to "crack down on crime." Individuals who make a political career about controlling others. It should be no surprise they then do not favor certain individual freedoms while in power and resent grunts who voice a different opinion.
Here is some situations Officer Leroy Pyle had because of his vocal 2nd Amendment support:

Some police chiefs have attempted to suppress dissenting voices in their department. For example, in San Jose, former
police chief Joseph McNamara wrote fund-raising letters for Handgun Control, Inc., on official city stationary, and claimed to represent what "every police officer" believed. In 1989, one of McNamara's officers, a firearms instructor named Leroy Pyle, was subpoenaed by the California legislature and legally required to testify before that body. Officer Pyle did so, on his own time, and out of uniform. The next day,
Pyle was suspended from duty, and McNamara attempted to fire him.
Handgun Control inc was the previous name of the Brady Center.
Here is a biography of officer Leroy Pyle, citing some of the problems he had by being a vocal supporter of the 2nd Amendment:

You mean talk radio? Well, they're trying to get rid of that right now. If the Left has their way, you'll have to listen illegal broadcasts on shortwave to hear anything but the Party line.
You think that is funny, check out this story:

ABC assigning a former Handgun Control Inc (Brady Campaign) member to cover gun related topics such as covering pro-gun events and legislation by the NRA.
So the public gets thier pro-gun coverage filtered through someone who wants firearms banned.
Unfortunately that is far from unique, and similar policies and situations exist in a lot of the media. They have agendas, and they make legislation happen. They can artificialy create an appearant immediate problem (like too many guns, shootings etc) by selective coverage, and then show people with a solution (banning X.) All while being "neutral".
