I do not believe in conspiracy theories till I don't have solid proof or evidence to comment. I believe this is not just headline management as one of the key aspects of it is to not do something that is self sabotage. Arresting Kejriwal is a big decision which can boomerang on the BJP if not handled well. Kejriwal is a popular leader chosen by the people with over 60 seats (in Delhi Assembly) twice. The move is dangerous and the people in the BJP and the government know it. The arrest before the elections and in the middle of the election process shows that there is a mentality in this country to decimate the Opposition at any cost and not have any level-playing field during the elections. Before Kejriwal's arrest, Hemant Soren was arrested, Congress' accounts were frozen. All this sends a message that the Opposition parties must surrender or they will not get a level-playing field in the elections.
