rosa rivera, president of the tenants' association. tell me, msvera, what is this all about ? exactly what are you protesting ? well, services in our building are very bad, and we can't get action any other way. you should try this ! rosa, you almost look good on tv. why, katherine you almost gave me a compliment. hey, look ! that's my arm ! i'm on tv ! there's that guy that said he was an investor. dr. steven martinez. i understand you own business interests in the area. is that correct ? actually, i'm one of the investors in this property. [ mcallister ] dr. martinez did you know about all the problems with the building ? absolutely not. i'm just one of a large group of investors. i'm not involved with the management of the building. doctor, many of the tenants here tonight appear to be of hispanic origin. as someone of that same background yourself do you feel any special obligation to get to the bottom of this ? this has nothing to do with nationality or ethnic background. i plan to take an active role and find out what's really happening... -
