He recently argued in a chat room with a Muslim, who felt he had insulted Islam. That man reportedly threatened to kill him if he didn't take back his comments.
Now of course there is a possibility that the family was robbed by someone who, perchance, used the same MO as a Muslim executioner...let's say 1000 to 1...and that's being generous. And I know police work...these gals and guys, despite the bad word spread, are humans with a desire for justice. In fact, their desire is quite strong...and strenthened by every frikken brutal murder they encounter.
I imagine the detectives and investigators on this case are like dogs...they may not find the culprit such that a trial can be brought and won...but they will know who did it and why.
And we can already speculate very accurately as to why...these Christians did not convert and had the audacity to speak truthfully about Islam.
This is the fate that awaits all of us...
Islam must die...we must kill it!
You have clearly identified the true enemy. It is Islam. And it is Islam that must ultimately be put on trial.
That individual should be easy enough to trace, especially if he was the one who traced the victim to his home.
I remember when I was getting a whole bunch of threats from RoP adherents on one site... I would trace their IPs (I always route myself thru at least one or two proxyservers, when posting on hostile sites) and then go look up an aerial picture of their location, photoshop a big red cross on top of their building and send it back to them telling them they had been traced, and their threats had been reported to their internet service provider, informing them if they were smart they would quit (such threats contravene the "acceptable use" policy of most providers).
It was very effective....
