Everyone wants law and order back in the society because no one wants to be living with fear, no one wants to be robbed on daily basis, the present day society actually need armed forces in other to maintain peace and order in the society because the activities of gangsters are becoming so worst by the day. some cities are trying in terms of security, just like Canada that you earlier mentioned they have the interest of the citizens at heart and cares a lot to ensure that there is peace and order in the state and every country should emulate that. but in some other countries like my own country Nigeria, the people that are supposed to ensure that peace and order are maintained are the ones committing crimes and even making the cities horrible for the people that they are supposed to protect. they also know the activities of the hoodlums but will fail to act instead they devise means to extort money from the citizens thereby making the city very unbearable for the citizens. for law and order to come back in every country, there should be a total and wholistic sensitization on the law enforcement agencies for them to understand the need for peace and orderliness in the state.
