>> THIS IS CBS NEWS BAY AREA WITH JULIETTE GOODRICH. >> GOOD EVENING. IT IS AN IMAGE SAN FRANCISCO IS TRYING HARD TO FIGHT. SCENES OF OPEN DRUG USE IN THE TENDERLOIN, AND THIS IS JUST WHAT YOU SEE IN BROAD DAYLIGHT. THE CITY SAYS WHAT IS HAPPENING AT NIGHT IS SETTING BACK THEIR EFFORTS, AND NOW THE MAYOR IS IMPOSING A CURFEW FOR RETAIL STORES TO CRACKDOWN ON LATE-NIGHT DRUG MARKETS OUTSIDE THE DOORS. THE PLAN WOULD IMPACT CORNER STORES, LIQUOR STORES, AND SMOKE SHOPS BETWEEN McALLISTER OAK AND JONES STREETS BUT THEY WOULD HAVE TO CLOSE BETWEEN MIDNIGHT AND 5:00 AMS COULD FACE FINES OF UP TO $1000 FOR EVERY HOUR THEY DO NOT COMPLY. >>> THE MAYOR SAYS THE IDEA CAME OUT OF FEEDBACK FROM PEOPLE IN THE COMMUNITY WHO DO NOT FEEL SAFE. BUT AS AMANDA HARRY TELLS US, SOME SMALL BUSINESS OWNERS SAY THEY ARE BEING UNFAIRLY PUNISHED. >> ONCE YOU ARE IN THESE STREETS, THIS IS IN THE THICK OF EVERYTHING. >> Reporter: JAMAR IS REFERRING TO THE MARKETS AT THE NIGHTTIME PLAZA. WHERE PEOPLE SELL DRUGS AND STAY UP ALL NIGHT. >> IS THE WILD WILD WEST. EVERYONE IS BUYING AND SELLING SOMETHING. >> Reporter: TERRY WORKS FOR SOCIAL WORKER A FEW BLOCKS AWAY BUT HE SAYS HE SHOPS AT PLAZA SNACKS AND DELI EVERY SINGLE DAY. AT NIGHT, THERE IS USUALLY A BIG CROWD, THAT IS BECAUSE IT IS ONE OF THE FEW STORES THAT STAYS OPEN AFTER MIDNIGHT. >> YAKIMA SEEN THAT MARKET, IT'S USUALLY OPEN BUT YOU CANNOT EVEN TELL IT IS OPEN, BECAUSE IT IS SO FULL OF PEOPLE. >> Reporter: NESTOR VASQUEZ IS A PRIVATE SECURITY GUARD FOR THE NEARBY FEDERAL BUILDING. HE SAYS THE LATER IT GETS, THE MORE BUSY AND DANGEROUS THINGS BECOME. >> SO MANY PEOPLE YOU CANNOT EVEN WALK. DEPOSIT IS FILLED, SS PD AND ALSO TO TRY TO DO WHAT WE CAN. >> Reporter: VASQUEZ SAYS MANY OF THE PEOPLE BUYING AND SELLING DRUGS WILL ALSO GO INSIDE PLAZA NEXT DELI, THE BUSINESS OPENED FIVE MONTHS AGO AND HAS BECOME VERY POPULAR BECAUSE OF ITS 24 HOUR AVAILABILITY. THE MAYOR'S OFFICE SAYS THESE LATE-NIGHT STORES MAY BE UNINTENTIONALLY CONTRIBUTING TO THE DRUG MARKETS. >> YOU KNOW, IT'S IS WHAT IT IS. >> Reporter: WITH THE STORE OWNER, HE DID NOT WANT HIS FACE ON CAMERA SAYS IT IS NOT THEIR FAULT. >> BLAMING BUSINESSES FOR BEING OPEN, BUT I THINK THAT IS THE ISSUE. THE HOMELESSNESS HAS BEEN GOING ON IN SAN FRANCISCO FOR MORE THAN 10 OR 15 YEARS. >> Reporter: HE SAYS MOST PEOPLE AT THAT TIME WERE JUST COMING IN FOR CEREAL AND MILK AND THEY NEED TO STAY OPEN. >> RENTON SEVEN CISCO GOES SO HIGH, OWNERS CANNOT AFFORD TO PAY RENT, AND EMPLOYEES OF THE SHUTDOWN EARLY. THEY WON'T BE ABLE TO MAKE IT. >> Reporter: A FEW DOORS DOWN, JAMAL ALI OWNS A SIMILAR STORE. HE SAYS THEY NOW ALWAYS CLOSE BY 10:00 P.M., SOMETIMES EARLIER, IF THEY FEEL UNSAFE BUT HE SAYS HE WOULD SUPPORT THE MAYOR'S LEGISLATION. >> IF IT MAKES A DIFFERENCE, IN MAKING THE COMMITTEE SAFER, I'M WITH IT. >> Reporter: EVEN TAMARINE, WHO IS ON HOW STEM CELLS SHOES ON THE STREET AGREES ABOUT HER SAFETY. >> IT'S A PRETTY ROUGH CROWD. >> Reporter: BUT HILLIARD SAYS HE DOES NOT THINK ANY LAW WILL MAKE A DIFFERENCE. >> YOU CAN DO ANY LEGISLATION YOU WANT, THESE PEOPLE WILL DO WHATEVER THEY WANT TO DO. YOU CAN'T STOP THAT. PEOPLE WITH ADDICTION, YOU GOT TO BREAK THAT COMMAND IS A SICKNESS THEY ARE INVOLVED IN, YOU CANNOT BREAK THAT JUST BY MAKING A RULE IN LEGISLATION, BECAUSE THEY'RE JUST GOING TO GO DOWN THERE TO ANOTHER STORE. YOU'RE NOT REALLY FIXING THE PROBLEM, YOU ARE ONLY MASKING IT. >> IF THE BOARD OF SUPERVISORS PASSES THE CURFEW, IT WOULD START AS A ONE-YEAR PILOT PROGRAM. IT IS A PART OF THE CITY'S WIDER EFFORT TO TACKLE THE DRUG EPIDEMIC. LAST MAY THE CITY OPENED THE COMMAND CENTER TO COORD
