I know what you mean, but somebody has to fulfil certain roles in court cases - Crawford presenting the case as best as she can, i.e. uselessly cos it's useless - give the judges the chance to ask probing questions which highlight the uselessness of the case.
It's like lawyers defending the worst monsters imaginable, being tried for rape or murder or something - somebody has to take the role of defender, and do it to the best of their ability, otherwise the guilty party could appeal because they didn't have fair representation, and maybe even go free.
'Only doing my job' is fair when it comes to lawyers, I think - somebody has to defend the bad guys, or it's not the system of justice as we know it..
I'd buy Crawford a drink, if I met her in a GC lesbian bar😁
