The weapons were held legally by registered gun owners, but police intelligence revealed 20 had "connections to family or associates who were persons of interest to the Acer Taskforce team".So any vague 'connection' to 'persons of interest' was all it took for them to steal private property. There is no 2nd or 4th Amendments in Australia. They can come into your home to 'inspect' and confiscate at any time. The same concept that 'safe storage' laws would create here.
Complete civilian disarmament is the ultimate goal of 'gun control'. For them to claim otherwise is deliberately lying to cover up the truth or they are lying to themselves.
