You are a plaintiff in the following case:

The police are appealing to a lower court against Nicky Shapiro. Shapiro’s son admitted to a murder that his father committed but due to the charter rights, self incrimination omits this confession. The police followed Shapiro home in suspicion against illegal weapons. When the search was done no weapons were found but 30 kilos of cocaine. Being a plaintiff, what arguments would you bring up?
