I am an atheist living in Pakistan, and incidents like these send a shiver down my spine. If this woman had not been sheltered by shopkeepers and the police had not acted quickly, she would definitely have been lynched and murdered.
The mob of zealots that had gathered around her was chanting "“Gustakh-e-Rasool ki ek hi saza, sar tan se juda, sar tan se juda”, which roughly translates to “what do blasphemers deserve? decapitation! decapitation!”
