Physical Assult Is Not Permissible

Physical assault  to anyone can never be justified.It is uncivilized  and barbarian act.For expressing displeasure with any political leader,there are many legal ways including street and ballot.The increasing number of attacks on the leaders are certainly a bad omen in the political arena.All should keep restrain and refrain from this lunatic behavior.It must not be permissible.
Punishment to the leaders  is  defeat in the election , and other  legal treatments.
At the same time ,leaders should also self analyse as to what is wrong with him , and correct accordingly, so that they must be dearer to the people.
