Sure, these peoples need to be fined and jailed. Make it a 1 day sentence for all i care, but now you have a criminal record.Problem is, all it takes is one dumbass like this jerk who think's this is all some big joke to (probably unknowingly) become a Typhoid Mary and those 4 weeks of complete lockdown are all for naught - doofus comes back from travel infected, doesn't adhere to the quarantine guidelines, infects 5 others in a bar somewhere, those 5 each infect 5 others (now 30 people infected), those 30 infect a few others, and away we go again.
Enjoy!
