Thomas Abrahamsen, an 18-year veteran of the San Francisco Police Department, was arrested on felony charges for building and possessing the most popular rifle sold in the Free United States.

An 18-year veteran officer of the San Francisco Police Department was arrested Tuesday on suspicion of manufacturing and possessing an assault weapon, a department spokesperson said.

Thomas Abrahamsen, 50, surrendered himself Tuesday and was booked into San Francisco County Jail on one felony count of manufacture of an assault weapon and one felony count of possession of an assault weapon, police spokesperson Sgt. Michael Andraychak said.

The arrest stems from an investigation that began last summer by SFPD’s Internal Affairs Division, which looked into Abrahamsen based on information from other department members, according to Andraychak.

The investigation allegedly revealed that Abrahamsen, a Berkeley resident, had manufactured and possessed a prohibited AR-15 assault rifle and AR-15 components, Andraychak said.

“In the spirit of the ‘Not on My Watch’ initiative, department members will continue to hold each other accountable and will act swiftly to report any behavior that might bring dishonor to the Police Department,” Acting Police Chief Toney Chaplin said in a statement.

Abrahamsen ran afoul of the law and may become a convicted felon despite 18 honorable years of police work due to the following mistakes:

1. He chose to live in the least-free state in the Republic.
2. He works for a police department that rewards snitching for violations of pointless gun laws.
3. He built the most popular rifle in the United States without a single small part required only in California.

Due to the absurdities of California’s ever-more-infringing gun laws, many firearms designed to use standard magazines must be equipped with a magazine release that requires a “tool” to release the magazine. The most common variant of that is a device called the bullet button.

Here’s another California law enforcement officer explaining what a bullet button is, and highlighting the silliness of the law.

A California-legal AR-15 equipped with a bullet button may take as long as 4-5 seconds to reload, making it so much more safer than a regular AR-15 magazine release, which takes roughly 2-3 seconds for a trained shooter.

Won’t that make us all safer? Of course not. All this law does is manufacture felons out of otherwise law-abiding citizens.

Here’s a bullet button in action.

If Hillary Clinton wins the 2016 elections in early November, however, you can rest assured that tens of millions of gun owners in the United States will be forced to comply with laws even more blatantly unconstitutional than those in California, as a President Clinton would pack the Supreme Court with left-wing radicals who would gut the Second Amendment with the sort of interpretations that drove the Founding Fathers to war with the King of England.
