MYSQL получить данные между и условием или условием

Я пытаюсь получить данные в виде JSON между двумя идентификаторами, которые имеют идентификатор пользователя либо Get['id'] или пользователь, который следует Get['id'] От других Таблица.

Мой URL — HTTP: // локальный / адитйа / м / Логин ID = 1&&начать = 6

if(isset($_GET['start'])) {
$query2 = "SELECT * FROM post WHERE (id BETWEEN '".$_GET['start']."' AND '".$_GET['start']."' + 3) AND userid = '".$_GET['id']."' OR userid IN (SELECT userid FROM frndlist WHERE followers = '".$_GET['id']."') "; }

Данные поступают в промежутке между 6 и 9 идентификаторами, но почему 5 тоже идет?
(постить в json как id) !!
