They need to bend over backwards with evidence because terrible shows like CSI and NCIS have convinced jurors that crime labs can perform magic and that they should acquit despite a preponderance of evidence unless there's a giant stack of lab reports and a manic pixie dream nerd testifying.

They should. Preponderance of evidence is for civil charges, criminal charges require proof beyond a reasonable doubt.

[hopler]

The standard in criminal law is "beyond a reasonable doubt", which is a higher standard than "preponderance if evidence" which only satisfies civil claims.
