In a society governed by law, everything is about evidence.
What is evidence?
The scattered bait left in front of Zhang Yang is evidence, but relying solely on this isn't foolproof!
Zhang Yang saw it with his own eyes and caught it in the act, seemingly solidifying the evidence, but if the staff slightly favors the identification of the bait, this evidence becomes insufficient. After all, the effect of fish driving is difficult to quantify, and it's not hard to manipulate the test process of scattered bait.
On this basis, can Zhang Yang produce the video of them lacing the bait?
Qian Wenjun, even with a calm mindset while lacing the bait, would inevitably reveal a guilty conscience in their actions. Upon careful observation, many of their gestures would betray their inner thoughts.
The laced bait is in Zhang Yang's hands, and the entire process video is also with Zhang Yang, so the credibility of accusing them of destroying the nest and poisoning skyrockets!
