Point taken. I still think it's absurd to have a federal investigation over some city's taxi regulations being evaded, but at least I can follow the potential legal logic. Thanks for the info.
So they misled investigators throughout multiple cities across the United States. Therefore, it's a federal issue. This really isn't that hard to understand.
No. Why it can be made a federal issue has been successfully outlined by others in this thread. Misleading investigators throughout multiple cities, however, isn't the reason.
