Childish acts by Pakistan

Pakistan police officials have said that they may stop their investigation in India’s 26/11 terror attacks. The reason they have given is very childish that they didn’t get proper cooperation with Indian officials. I was really laughing when I read this news. I don’t know why Pakistan officials are behaving like this. They agreed that 26/11 terrorists came from Pakistan, but they are telling they won’t investigate. I really don’t understand the logic in this. Pakistan themselves accepted that a part 26/11 plan was executed from Pakistan, but now they are telling they won’t investigate in this matter. I have just one thing to say, Pakistan’s act is really childish.
