There needs to be a concerted message from Government that instructs people to remain indoors and that the repercussions for refusing to do will be punitive rather than suggestive.
Civil liberties groups also need to respect the wishes of the people who wish to stay alive.
Personally i'd send them on Holiday to Tunisia as people who flout the instructions there will be charged with manslaughter if their is an indication that someone has contracted the virus from them and dies as a result. That focusses the mind on taking notice.
