To be honest I liked batman a lot, all the way up to where he said gunshots before bat

, right then I knew something was wrong so I paid attention. And minutes later I understood what he was saying, he was conflating that the bat strike marks and the bat being used to pry the panel loose happened as one event. He did that wrongly IMO, but innocently too. He works in a laboratory and has decades of experience in this stuff so it is a huge part of his life, but in this case him being isolated from even reading OPs affidavit led him to make that wrong statement. He did clarify that it was not scientifically possible to say with certainty which came first, bat or gunshot, so again I see him as a dedicate professional and he did a very good investigation.
