Definitely a forward cant/FBI cant hides your gun better. An FBI cant is 11-degrees (IIRC) but you don't necessarily need that much cant to conceal. Really depends on your body and where you wear the holster.
Personally all my holsters are straight up and down (no cant). Holster at the 3-o'clock position, by the arm. I find it easier/more natural to get a proper grip and drawing.
There are at least two sides to every story. I just heard yours and, indeed, you appear to be the victim. But I can't stop wondering what the other side has to say.
Oh, g-d, if only LEOs can be indemnified from willfully ignoring the stupid!
