If you go to any public place and still some public is around, the police personal will not ask you but if you are alone he surely will ask you. This is one way to make sure every thing is ok with you and to make sure nothing is fishy going on. Some times some one may be having some medical issue and can not leave with out help. Its good and not good some times.

If me I will not prefer to go alone in early morning. I dont like someone come to me and look at me with suspition.

Try to avoid if possible or otherwise go as group.

Peace.
