SECURITY & VIGILANCE has no authority of detention; hence despite a will for stern action, the action as per legal dictate has to be restricted to a more facilitation i.e. collecting beggars and handling them over to police and if police shows inability to detain, the beggars are dropped off outside DHA; needless to say how fruitful that can be.
The real issue here is that as long as these professional beggars continue receiving charity, they not only would keep coming back but will keep increasing as well.
