Ig bars spy policemen from wearing uniform

I think there may be a bit of a misunderstanding here!

IG stands for "Inspector General", which is a high-ranking law enforcement official in many countries. In this context, it's unlikely that IG bars (which are a type of food) would have any authority to spy on policemen or restrict them from wearing their uniforms.

Could you please provide more context or clarify what you mean by "IG bars"? Are you referring to a specific incident or situation? I'd be happy to help you understand what's going on!
