What does a MUSLIM think about the Knife Attack of the Soldier that Happened in Woolwich?

EDIT: It hasn't been confirmed as to whether the criminal was a Muslim or not. I shouldn't have jumped to conclusions. But in the case if it is... please read on. 

Here's what Islam says about the beheading that happened in London by the two 'Muslim' men:

"That if anyone killed a person not in retaliation of murder, or to spread corruption in the land – it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind."- Quran 5:32 

“Whoever kills a mu‘aahid (a non-Muslim living under Muslim rule) will not smell the fragrance of Paradise, although its fragrance may be detected from a distance of forty years.” Narrated by al-Bukhaari, 2995 (let alone a non Muslims living in his own land!)

Words cannot express how frustrated I am. A couple of pseudo-mujahideen thinking they would have the glory of martyrdom by BEHEADING A MAN ON THE STREETS OF LONDON and shouting 'Allahu akbar' when doing so. This is not jihad, this is barbaric mindlessness! And WE as British Muslims are left to pick up the pieces.

What fate have they left for us British Muslims?

So many British Muslims will suffer as a result; whether it be physical attacks, racial profiling of Muslim men, unemployment, Muslim mothers, women and children being taunted on the street, hijabs being ripped off or reactionary laws against us. I hope it goes all on their record on Qiyamah. And as for those who are discriminating against us Muslims, it's obvious that most 2.8 million of us are not like this. So be quiet. Of course there is a bias in the discourse of the media. But nevertheless what happened was completely against Islam as I have shown above.

You know, this ayah (verse of the Quran) comes to mind when thinking about what the fate of these mindless men could be. I do believe that there were attempts by Imams, parents and other fellow Muslims who tried to talk them out of their extremism:

"They will further say: "Had we only listened or used our intelligence, we would have not been among the inmates of the blazing fire." (Quran 67:10)


EDIT No2: It hasnt even been a day and already Mosques are getting attacked. As British citizens we have to unite against extremism as well as bigotry. These two groups have so much in common.
