The advice on the thread is dead right, get a good brief..!
But just to give a bit of perspective, around here, full permo or not, i've never carried the smallest of blades, nor have i worn cammo clothing, nor nothing but the best country attire or none country attire...
Thing is, there are little scrotes being pulled all over the country. They don't give a f**k. Easy come, easy go. There indifference to the law is changing it constantly....
Wise up, the world is changing....
Best of luck... ?
