This has always been interesting to me.  

I don't believe that a real lawyer would allow his client to be convicted for prostitution for having condoms.

Condoms are not illegal.  Condoms are to protect our health.

If the LE can get a conviction for a lady having a lot of condoms on her then: A. What is considered too many condoms?

B.  Shouldn't the condom companies start putting a warning label on the box stating "If LE searches you and finds X amount of condoms on then you will be charged with prostitution"?

Sounds silly I know but it really annoys me when I hear of an arrest in the media and included is that LadyA had X amount of condoms on her.

You didn't have a link, so I can't see the full story, but I can assure you that there was more evidence than just a lot of condoms.  If that is all the story had, it was inaccurate.

In fact, think about it for a second.  How did the cops even bother to go to her place.  They must have found her through an ad or some other means.  I would wager that there was other evidence also.  "Get comfortable."  "300 roses."


If there is a lot of other evidence of prostitution, having 300 condoms may be SOME evidence,but it would only act as corroborative for the other evidence.  

Trust me. I know evidence.

I can't imagine how a lady could be arrested or convicted for any sex offense solely bc she had a lot of condoms on her person.

Client was thrown out of her incall for "misbehaving" and he called the police and filed a police report.  Accusing the lady of running a prostitution ring out of her home.

Cop showed up at her door and lady got scared and let the cop in and he started searching her place for condoms.

Cop said that if he found condoms he was taking her to jail.

In my opinion she should not have let the cop in without a search warrant.

So often we just let the cops do what ever they want because we feel intimidated by them.

Just politely say that you will not allow any entry without a warrant and that in accordance with your rights under the Fifth Amendment, you have nothing to say.

I hope she outted this client and put him on all the DNS lists that there are.

(still not a lawyer)

Yes letting LE in to your home is a definite no. Even if you have nothing to hide, it is still an invasion of privacy and your rights under the Constitution.
My legal advice to providers is this. If a LE official knocks on your door, you are entitled not to answer it. If you feel you must answer the door, either make sure you have a barrier (ideally a security door) between you and the officer. The officer must state why they are calling on you. They will probably say 'they have recieved a call about....'. Usually LE will say a disturbance. Obviously, you will deny this and they will request to come inside and check. Politely request your rights to refuse under the 5th Amendment.
If you open the door to LE and they have a foot inside your property they will claim they were invited in-yes this is questionable.
If LE claims to have a warrant to search then they must show this warrant and you are allowed to read it. They cannot refuse to give you the warrant until you let them in-this is a trick LE do use when they do not have a warrant. It is your word against theirs and the courts will invariably side with LE.

The best advice I can give to providers is that they install a security door and a camera. The security door will allow you to communicate with LE without allowing them any access. A camera can record any encounters and you can warn LE that they are under surveillance-please make sure that you erase the recordings daily if you have many incalls-as much as this can protect you it could incriminate.
Finally, the evidence of condoms would not alone be sufficient evidence to convict. LE would need more evidence that would suggest to illegal activities.
