Thinking quietly, I feel that Lockdown was done because Tablighi Jamat conspiracy was already unearthed and due to Lockdown they would get little crowd to spread infection.

And after Lockdown was taken to a controllable level, they opened this case.

Just a benefit of doubt.

I am saying this because on 21st March 2020 Union Govt informed State Govts about this Tablighi matter. Which means they got the big picture by 20th March At least.

On 20th March 2020 at 2000hrs @NarendraModi announced #JantaCurfew

Once an enabling atmosphere for Lockdown was made through #JantaCurfew, Modi ji announced Nation-wide lockdown.

I am saying, a slip did happen, but they were trying to contain it in best possible manner. That is, through a 21 Days Lockdown.
