The Black Lives Matter demonstrations continue in the United States and there have been riots in Wisconsin for several nights.

On the night before Wednesday Swedish time last week, in addition to protesters, loosely composed groups of armed people appeared who were said to want to protect society.

One of them was a 17-year-old Trump supporter who lives with his mother in a quiet apartment area in Antioch.

He is described as a person who regards the police as heroes.

Carried with automatic weapons

The 17-year-old traveled the more than three miles to Kenosha, to, according to his own statement, protect local entrepreneurs from being looted during the protests.

He had with him, among other things, an automatic weapon.

"Part of my job is to protect people and I have my rifle to be able to protect myself," he told the Daily Caller the same day.

But the riots came to degenerate when the 17-year-old shot dead two people where parts of the course of events were captured on film.

It is unclear what started the incident, but a person is said to have thrown a plastic bag at him.

Arrested in his home

In addition, an unknown shot was fired and the 17-year-old responded by shooting dead the person who threw the bag.

He then ran away from the scene and was then chased by several people who tried to stop him.

He lost his balance, fell to the ground and then fired his weapon several times, killing another person and injuring another.

He then went towards police cars with his arms in the air but was not arrested despite people shouting that he had shot several people.

The 17-year-old was instead arrested the next day in his home and will now be charged with two murders and one attempted murder.

However, his lawyer claims that he acted in self-defense.

Posed with weapons

American media, including the Chicago Tribune, say that the 17-year-old dropped out of high school two years ago and on social media there were pictures of him holding a weapon together with a Black Lives Matter logo.

After the arrest, his Facebook profile must have been deleted.

The 17-year-old will previously have been tested on volunteer work where he was allowed to accompany police for a year.

It is described as an initiative for people between the ages of 14 and 21 who aspire to become police officers.

Now the 17-year-old's actions have become big politics in the US where Donald Trump defends him.
