Raj said he wondered why no questions are asked to state government over delay in making arrests.
"Had the government cleared anti-superstition Bill earlier, Dabholkar's murder could have been prevented", he added.
The MNS chief also unveiled a booklet on the Anti-Superstition and Black Magic Bill.
The Bill was recently approved by the state government following growing public outpouring in the wake of Dabholkar's murder.
