How to stop Law enforcement entering a website ?

Hi, can I ask , is there any way I can put up a entry sign to my website that will , once enters clicked , stop any law enforcement entering or if they do , there rights do not apply with in the site.?

i have a site that encourages people to talk about drugs , misuse of drugs and info on drugs.

people do not want to talk openly if the police are aware of it or can track the members on the site.

thank you for any help.

Please .... Do not comment if the site content ( drug info ) is against your beliefs , simply move on to another post. Thanks.

Anything on the open internet can be viewed by anyone unless you can identify each specific user and block them.

The only way to be secure is to use the dark web. Even then the law can view what is posted the only difference is they cant get your information like IP address and stuff.
