Do you have any idea how many ways there is to circumvent Rule 144.
The 11 companies for acquisition was a way for Costello to obtain shares to dump - but COWPP was suspended and that put the brakes on Costello along with his arrest and the CANN lawsuit.
Plus, we know that Costello doesn't care about lying in an 8-K or just not filing. So there isn't anyway that you know what Costello has sold.
