one of the pro guys left his marker at home and didn't lock his room. His relative had fun with the marker and shot at a few houses from far (condo) and almost hit my daughter. This was during a function I held a year back. My sis had a telephoto camera and managed to figure out which house it was. The good part was there was a jersey hanging at the window so I managed to contact the team lead. He was defensive at first but later his teammate admitted that his relative used his marker.
I used to play pball too and I know about the safety rules in Malaysia. I was shocked to find that the guy can keep a marker at home. During my active pball days, we were told that markers can only be kept at police stations or by those with gun license.
