The brother of a 20-year-old Florida man charged with threatening on the Internet to re-enact the Virginia Tech campus massacre says he never intended to hurt anyone. Vincent Wong says his brother, Calin Chi Wong, just had a stockpile of assault weapons and thousands of rounds of ammunition at his Homestead home for investment purposes. He says Wong traded the weapons like "Pokemon" cards. Police say the US-born Calin Chi Wong had 13 firearms in all, including two sniper rifles, more than 5,000 rounds of ammunition, some that could pierce armor, and 100 rounds in a feeding clip with bullets designed to take down aircraft or military machines. Police say he made the threat over the Internet after he felt he was ripped off in a gun deal.
