What does it mean if we "go from there"?
This was taken from a June 2011 story about implementing drug dogs at a nearby high school. Story: https://patch.com/california/hermosabeach/drug-dog-recommended-for-ruhs-2
The student board member was concerned about the dog's power of smell, asking if it is safe to solely check the lockers. The assistant superintendent joked "maybe", reasoning that the school needs new lockers for this reason. However, he notes that when the school and police find drugs in a locker, they investigate. The school resource officer describes that "they will talk to the student who supposedly had the locker and go from there".
