surprisingly we are seeing in most cases that whenever CBI takes case,they took the concerned person's desktop or laptop...And they find lot of evidence from there !!! Really a person records some good evidences in thier Laptop or Desktop before committing Crime (Arushi case),or before being murdered (Arushi and Rizwanur case) !!!!!How they found evidence in those machines..???? Interesting !! Hai na ! God bless that CBI can found the right thing,instead framing some innocent people.Till now CBI's record of Investigations are actually very less effective than local Thana's investigations.We could not see good results.Till now we dont know what exactly happened to Rizwanur and why CBI failed to address some questions asked by the people and Media.... How in Nithari killing,the house owner got scot free.... And so on....
