lets not put the pressure on the police personnel, ulltimately they are given guidelines to follow , i call them law enforcers.
i think its more of the law makers who set the rules n laws, they should revisit the whole issue of assualt on others. if they cannot bring themselves to craft 1 out, enforcers basically have nothing to act on.
police can only act only when there is a case open , hence the term "file a police report", we are all paying for their time , so a time well spend on a good case justifies all.
i think if there is no noticeable signs of injury , police officer cannot do anything.
