Is there anything I should be doing to ensure that the badge worn by a person belongs to THAT person? LOTS of talk of badge sharing, bootlegging, ghosting and lobbyconing with the sell out. 
If there is an obvious badge issue what should I do?

Public shaming, pulling out by the ear, and throwing Catan foam bricks at them are all acceptable forms of punishment.

Is that really your concern?  I would think that as a game master, you would just want to make sure everyone has a badge.  Unless you want to go through the trouble of asking everyone at your table for a photo ID.

If you have a concern about the validity of a badge, you can report the concern to the nearest HQ.

If you see something blatant, *and* you're near a Staff member, Event Team or ICC security, you can try to point it out to them, but really, unless it happens in front of them, the ghost will probably disappear before they can be caught. 

If you're a GM, your duty is to make sure people have a badge, and that's it. Not to ensure that the badge belongs to them. Unless Derek has sent you something to the contrary...

Gen Con doesn't need to become a police state, everyone should just be more diligent about what they are already supposed to be doing: make sure all players have a badge and a valid ticket before the event begins, to avoid any issue later.

If you see something obviously suspicious or problematic, let a nearby staffer know - I would not recommend any sort of "citizen's arrest" or anything.

As a GM, your responsibility is your game or event, not the convention as a whole - but definitely let us know if you see anything weird so we can deal with it. That's our responsibility.

Awesome! Thank you!

That concerns me... the last thing anyone should want to deal with is folks without the proper authority or training attempting to enforce rules they may or may not completely understand.

If someone wearing a security shirt or official staff badge wants a closer look at my badge or to check ID? Great. Anyone else is going to get ignored, and if they persist reported for harassment.

Badge yes, photo ID no. Of course no one is going to refuse to show a badge... is that really what you inferred from what I said? I'm concerned about well meaning people trying to play 'Spot the counterfeiter'. Leave that for security and the staff.

Yes, by all means, ask me to show you my badge. If you want me to take it out of it's holder so you can closely inspect it to make sure it's valid? Different all together.

You posted before I could post.  Not to be ripping on you because if I'm walking through the con and someone asks to see my badge who isn't wearing a gen con staff, security or someone I know works for gen con my response would be "go f yourself". And the f would be the full word.  
As for checking badges all I do is look to see you have one and if not a four day it's good for the day of the event.  Since you can buy tickets for friends and family I don't even check the name on the ticket with the name on the badge.  Just that both are good

You can tell I'm bored and getting itchy, hanging out on the forums, waiting for next week to roll around.

This time next week I'll be wrapping up my second game at The Ram and getting ready for the beer and music on Georgia Street.

Alright guys, chill down. no need to strut and posture.  No-one is asking to see your papers.

Just asking IF there is something I am supposed to be doing. Relieved to know that I can just run my events as usual :) 

Nope, just run the best darn game you can :-).
