One could also ask you to not excuse the equipment, but that would run counter to the accepted wisdom of paying more and getting less that seems to be the prevailing wisdom here and elsewhere?
So don't excuse the equipment then. Blame Canon. It's Canon that designed a lens release solution where quite a number of people - with or without any BR - have dropped lenses.
Any other equipment where $10000+ is at stake would have be designed with a more fail-safe solution.
