This is a bit confusing since in the "pass" case, return m_reportOnly would return the inverse of what you wanted.  Maybe this should be some helper function?  I'm not sure the name.  falseIfEnforcingPolicy()?  !enforcingPolicy()?  false || m_reportOnly?  I'm not sure.  This may be fine as is, just smells a little funny.

The "pass" case is handled two lines above.  This return statement is only encountered after we've fired off the violation report.

I can see wrapping it in a function though.

return denyIfEnforcingPolicy();

Of course now it feels like we should have an Allow/Deny enum (mapping to 1, 0 of course). :)
