Investigation and fact finding are just the procedures. "Unless and until the highest court convicts a person, you can not say that the person is guilty," Das said.
He was responding to questions on BJP's charge that Congress was trying to frame Modi in the Ishrat Jahan case.
"Congress has a pathological hatred against Narendra Modi even though people adore him for impeccable integrity and outstanding record of governance. In spite of repeated defeats in elections, CBI is being abused as an instrument to frame him on questionable, collusive and spurious testimony," BJP leader Ravi Shankar Prasad had told PTI on Friday.
Unimpressed by the Union Cabinet's decision to set up a collegium for choosing CBI Director, BJP had also alleged that the government was not serious about granting autonomy to the probe agency and continues to misuse it for political gains.
Countering the allegations, Das said at a time when the government is talking of giving autonomy to the probe agency, is it relevant to "raise fingers on CBI".
He also hit out at BJP over the continuance of Gujarat water resources minister Babubhai Bokhariya even after his conviction by a sessions court in a illegal mining case.
