Just because this guy was from Brazil doesn't necessarily mean he wouldn't have links to terrorists (including Islamic radicals.) (Ref.:)
RIO DE JANEIRO (Agence France-Presse) - The high command of the Revolutionary Armed Forces of Colombia has three bases or hide-outs in Brazil, the daily O Estado de Sao Paulo reported during the weekend, quoting Colombian intelligence sources.
The report said the largest of the bases is in the southern Brazilian state of Parana, in a region known as Guaira, on land owned by a naturalized Brazilian of Lebanese origin who has been in government custody for seven months.
Hopefully MI5 and MI6 are checking out this guy's background while Scotland Yard is getting "Monday morning quarterback'ed" on this shooting.
An electrician would be a good cover for a bomb maker. If they get any explosive residue off of this guy, then this may have been a righteous shooting.
Hopefully the bobbies had a little more than a hunch and a suspicious runner to back up their choice to take this guy out.
"Hopefully MI5 and MI6 are checking out this guy's background while Scotland Yard is getting "Monday morning quarterback'ed" on this shooting."
Well, it's the Met Police who are the ones who have said that the shooting was a mistake and that the guy was innocent...
I thought about FARC, too. They are big on car-bombings and were supposedly trained by the IRA. In fact, a couple of years ago, one of the IRA's "best" bombmakers was nabbed in Brazil, where he had gone to train FARC members and members of Islamic radical groups in bombmaking techniques.
Being an electrician from Brazil certainly does not make this man seem less suspicious.
