The answer is that "it is more difficult to prove mens rea in an attempted crime because attempt is not a completed crime."
Strict risk offenses which can be submitted without evidence of mens rea exhibit by lawful authorities. In this sense, is it reasonable for rebuff the individuals who did not plan to cause hurt, but rather accomplished so because of numbness? Then again, it would be to a great degree hard to demonstrate the mens rea on a few offenses, for example, motoring offenses. Besides, it would force an extensive weight on the criminal equity framework.
