Stealing or not , their system if failing and their dollars are fading.
You'd be scared and agressive as well if it was your job.
What if there's this big pond where people can drink from , for a fee and it's forbidden to take any water out of it without paying the fee for it.
Now , there's this smart person who heats up the pond , makes clouds and hope it'll rain on his property ,so he can drink for free.
No biggie , since that's also the method that the pond is filled with nice fresh water , but everyone notices the guy and they all start like heating up the pond. No biggie as well ,since it rains enough around the pond , to have it filled at all times..
but ... somehow the owners of the pond , lost a great deal of their income. They get agressive and tell those idiots that heat up the pond , to stop that , because they haven't paid for it. They even convince local authorities (for a free drink) that it's illegal and it always was illegal.
Who would you rather be ? The owner of the pond , or one of the "hopefully" free drinkers ?
