Why now NOW, Boris. Why wait?
“Why wait?”
Assuming this is true...
A new law or policy goes through a process. It gets approved in principle and then it gets drafted. The draft is reviewed and approved, a process that could take weeks. Then it gets published and disseminated. A date is set for when it takes effect. This process has to be followed as the various organs of the government do not take verbal orders. Whatever law is on the books is the law until it has completed the process and been disseminated.
Let’s say the new law says no spitting on the sidewalk, but this law sunsets at noon tomorrow. If organizations took verbal orders or said, “Heck, it won’t be the law this time tomorrow so I won’t’ enforce it.” then in some areas and by some police it would be enforced and in other areas it would not. This would create chaos as people filed lawsuits. People who had been cited would point at people who had done the same thing and had not been cited. The courts would then ask, “was it illegal at the time? Then guilty.” This is an overly simplistic example but scale it in your mind to all the myriad problems it might cause in the various rule driven organs of government if verbal orders were allowed. This is The Rule Of Law. The fact that it moves slowly is, overall, a huge advantage.
