What S. 18 means by these words is that the officer or the authority must consider that the person who holds the licence was likely to use the fire-arm in a way, which would endanger the security of public peace. This result cannot be achieved in a roundabout manner by considering that if the man was brave or courageous, and used his fire-arms, it might have assisted in keeping the public peace.
