THe issue isn't the laws it's how police are interpreting those laws.
Police minister yesterday said Shopping at Ikea or other retailers was not essential. Yet Ikea are still open as are many other stores that sell non-essential [in the ministers eyes] items.
He then said, words to the effect that you have been warned and it's up to police discretion whether or not you get charged.
It's all policy on the run and pretty much anything you do now is a roll of the dice whether you get fined or not.
Fishing is no different in that it's not an essential service which means that you will most likely risk being fined or sent home if police decide to go with that option.
THe laws on all this are so vague nobody really knows what's going on - because senior ministers have come out and said fishing taking into account social distancing laws is permitted.
It's ridiculous.
