Im a Dcopsian.............and I learnt Judo and Karate.....later taekwando and whushu after I left school......If you have not studied in DPS then you do not know about gang attacks are either......So your Kata is good for few , but when a gang attacks you need a gang to fight back.....Believe me in DPS we had plenty of one on one fights but when things got far...........even the GURUS couldnt stop the Dhutureys and the Dhukureys to clash......Rods knuckles bricks etc etc were used ........Martial arts goes out the door ......Its fight or run.......oh yes in the above picture It shows the kids flexibility not how tough he is ..........get it
