What are some of the steps you do when an adult is missing Vs a kid?

Well, firstly, I think you have to legally wait twenty four hours before they're legally considered missing and before the police can take action. I think this is a "dumb" law or rule as the first twenty four hours are essentially when they have the greatest chance of being found.

Secondly, a difference in missing adults verses missing children is that adults CAN simply leave without saying goodbye, whereas children really cannot without being considered a runaway.

What if you go to the ploice and they say theirs nothing we can do?

I find that people do not like to give out information

where do you go for information without a lot to go on?
