Right...... two weeks is only enough time for people who are infected today to be showing real symptoms, so at the end of lockdown they’d still be spreading Covid.
Very strict lockdown still means NHS, bus, train, taxi drivers, supermarket staff, bank and finance, some teachers, some nursery, police, soldiers, utility workers etc are still working.
The lockdown would have to stop anyone from entering or leaving the country, Nobody leaving their house at all, not even to walk the dog or take the flat dwellers kids to the park.
Total lockdown would mean telling Ireland not to cross the border into Northern Ireland, would you suggest enforcing that with troops and breaking the Good Friday agreement?
Nice idea, but 100% impractical to have a “very strict” lockdown.
