Yes. Suicide...
That's what the paper work likely says. Although, in my experience.
There are times when suicide is labelled as the cause of death when murder is the cause.
I believe such suicides aren't that uncommon when it comes to people who are criminally minded which includes those who prescribe to far right political views and in some cases, those who practice "ritual" "magick" (perhaps to Norse Gods of War, as suggested by some of the rioters tattoo's).
It is also possible in some cases that such people are also employed by the Police.
It doesn't take a genius to pull off a murder, it just takes some calculated risk and a belief that you are right in what you are doing.
In such cases of National Politics, which has aspects of White Supremacy involved, people who subscribe to strategies of the WW2 nazi's. Taking one life isn't that much, if it gets them closer to their goal or punishes those who they blame for their defeat.
I believe that loads of the crazy things that have happened around the world over the past 20 years, have been related to the same type of person. Whether they be related or perhaps even linked.
As we have seen time and time again, as soon as things go pear shaped, the blame is then aimed at one of their enemies, in attempt to get a win out of their loss. i.e. it was the democrats, it was the Muslims, it was the Jews...
The technique they are using when they do such things is called Misinformation. This misinformation is then spread by unassuming public, which then converts the misinformation into disinformation.
Which although not necessarily done intentionally, it is as damaging as the misinformation.
This is the wonders of propaganda and the impact of propaganda on the unassuming public.
Always check the sources of the information that you read, as not all information is equal!
On a sad note, if it was a genuine suicide, perhaps you could understand why he would do this.
As for the rest of his life he will be known as the Police officer that let the Rioters into the Whitehouse! Doh!! !
Imagine what his life would be.
Although he could have potentially sold up, cashed in his tokens, and gone and lived in some far off country where no one knows his name nor cares.
