You may add that tcpdump works "outside" iptables. That is, it sees incoming packets stopped by iptables and it does not see outgoing packets stopped by iptables.
The original issue was opened on 2009-07-18. The only immediately actionable work item I can tell here is to make the error messages consistent with the man page.
On the note of Linux BPF placed "outside of" iptables, on FreeBSD this used to be exactly the opposite: tcpdump never sees incoming packets rejected by ipfw
