When some one kills innocent people through bomb blasts then it is called a crime and Islam considers it a great sin. When some one kills Pakistani law enforcement personnel then it is also called treason.
When you through term like "islam" in, make sure once prophet said "empty stomach can take you to kuffer"
Reason I quoted it is, There are other factor involved here rather then just talibans counsious as being muslims.
I am talkng about Mush, every one (even ppl on GS) predicted this situation when mush wanted to bomb lal-masjid to prolong his rule.
