If there is suspicious activity with your bank account the courts will give a court order. And of course your bank monitors everything, they're the ones responsible for your money.
The IRS also has information through your tax report, but why would you want to increase the number of federal employees? Because you know benefits go along with the salaries. And federal employees are rarely fired...so we'll all be paying for that action, as will be our children, and grandchildren, Does that make sense?
