Since Go is lexically scoped, you can assign value_variable inside the function you pass into View:

var value_variable []byte

// Access data from within a read-only transactional block.
db.View(func(tx *bolt.Tx) error {
    v := tx.Bucket([]byte("people")).Get([]byte("john"))
    value_variable = v // <----- ASSIGN IT HERE
    fmt.Printf("John's last name is %s.\n", v)
    return nil
})
