Yup, INTEL costs... My worry is you will find something so condemning that you will be enraged and throw it at him... Which is the LAST thing you want to do...
When you start collecting intel and REVEAL it to him you OUT yourself and your intel operation and he will shut it down on you...
Collect the intel and act on it but give no indication to him you know anything...
This reverses the affair dynamic because before HE knew more than you did ... Once you start an intel operation YOU are in the know and HE is out of the loop...
It's hard to pull off but the info is there... Do you know any tech savvy people in your area who would be willing to help you?
