Police Officer needing further defense training?

It seems that we are locally trained in some jujitsu. The training is fast and carried out very seldom. I need to know what would be a good all around martial art that would give me good ground fighting, great stand up fighting, and real street fighting training. I have heard kung foo san soo is good in all of these areas but I feel like there isn't much ground fighting leverage with someone who knows jujistu. I am torn between the two, mostly because I really am not interested in gi fighting but love the principal behind bjj, especially with the idea that any fight will be eventually on the ground. Kung Fu san soo offers submissions, and a good stand up , and all around seems more natural and brutal. But if I was on the ground with a guy trying to fight him and he happens to know jujistu, does that mean I should have been learning jujitsu instead of kung fu. Or maybe learn both? please say there is an all in one solution that will be easy to comprehend.
