Liverpool in the last few days has seen a surge of taxis with plates from Warrington and Manchester, which would suggest people are coming to the city.
Good for business? People just going for meals? Maybe. The flip side to your point is that these areas are under restrictions because of their increased rates.
As such, they are potentially bringing the virus here, which can increase transmission - that may cost lives. Should the police just ignore such transgressions?
The restrictions are in place for a reason, and it would be much easier if people abided by the rules and we would therefore not require such 'pathetic' actions.
Personally, the law has to be upheld objectively. It's like when someone moans that they only parked on the white zig-zag lines out of a shop for a minute.
"Haven't they got something better to do?" Well no, and people wouldn't moan if they had actually witnesses the potential consequences...
... "Sorry your son was run over and killed because they stepped out, when their crossing light was green, but their view was blocked by a car on the zig-zags."
It's not about going for a meal; it's about stopping the transmission of a virus, which may kill someone.
