You and I disagree on the reasonableness/ desirability of true US castle doctrine - but I think there's a massive opportunity for a well intentioned political push to legislate away the "loopholes" that judicial activists use to go after home owners (PAL holders or not) in self defense situations.
I agree (and have posted to effect) in the principles of self defense requiring a fair degree of restraint and discretion on the part of the defender, and shouldn't allow carte blanche for escalation or an "advance to contact" so to speak. That being said- the degree to which pacifist judges have set the table so that "too much" preparedness can be construed as a breach of Section 88 Possession with a Dangerous Purpose, or that active deterrent use can be found as breach of Section 86 Careless use is absolute horseshit.
Case in point- due to the layout of my home, and the positions of my neighbour's homes I'm really not comfortable with the arcs from my bedroom to door to deal with any intrusion, so I'm considering getting a Byrna. Common sense would say that should be favourably looked on by the law, less of an escalation, can defend without killing, etc. But nah- purchasing it expressly for said purpose violates section 88.
