I remember when I was working with .NET and I saw some web service code and I saw there was no try catches. They didn't have a global catch in the asax either or anything. I just wrapped each call into a try catch and log.
I got the same treatment where my manager wanted to know what happened with the increase in errors. I told him what I did. My manager got another developer to go through my commits regardless. I was a bit upset at the lack of trust.
