How do you say §511どんなアリバイをでっち上げても、証拠を見ればおまえが犯人だと分かるのだ。事件のことを洗いざらい正直に話したほうが身のためだぞ。さもなければ、陪審員の心証を悪くして立場が不利になるぞ。 in English?

No matter what alibi you may fake, the evidence shows that you are the criminal. It's good for you to confess everything about the incident with honesty; otherwise you'll make your standing worse, giving a bad impression to the jury.
