"At the officer's request, Jackson handed over two grams of unburnt cannabis he kept in a baggie in his glove box. Possessing up to 30 grams is permissible under Illinois law."

"Judge James E. Shadid of the U.S. District Court for the Central District of Illinois came down in favor of police, ruling that Jackson had run afoul of the state requirement to keep marijuana in an odor-proof container."

"Twenty-three out of 50 states, along with Washington, D.C., have legalized recreational marijuana. "The simple smell of something that has a host of perfectly legal uses in a state should not be sufficient grounds for police to prolong a traffic stop," Paul Sherman, a senior attorney at I.J., tells Reason."

"At the core of Jackson's appeal, and I.J.'s brief, is the Fourth Amendment's promise that people be free from unreasonable searches and seizures. In that vein, Nelson maintains that unless the judiciary clearly defines probable cause under such circumstances, police may be incentivized to weaponize their power in perverse ways."

""Vigorous judicial enforcement of probable cause is particularly important in the context of automobile searches, which are typically conducted without a warrant issued by a neutral judge," said Nelson in a statement. "Because of abusive practices like civil forfeiture—which allows police departments to seize and keep cash and other property merely suspected of being involved in a crime—those officers often have strong financial incentives to search, regardless of whether probable cause really exists. If judges don't closely review those decisions, drivers are left with no protection from abusive searches.""
