I'd heard this before, but not that the officer's remark was "testimony." I'm also not sure what significance the remark has, anyway. Nobody disputes that the affidavits are identical except for the names. The dispute is whether or not those allegations create probable cause.
A police officer testified a justice of the peace approved the affidavits without making any individual determination of probable cause.
They brought the officer who signed the affidavits to testify at property seizure hearings.
