I don't blame the police for not believing people even when they tell the truth ....

how can they be sure you are not lying when they come across liars like the woman  below every single day they are on the job?

From Yahoo:
A Michigan woman accused of lying for years  about having cancer was convicted Thursday in a separate case of falsely accusing two men of rape.
The jury took less than 30 minutes to convict Sara Ylen after a three-day trial in St. Clair County, 100 kilometres northeast of Detroit.
Ylen was charged with making up a story of two men attacking her in her Lexington home in 2012. Ylen, 38, was also convicted of tampering with evidence after police said she used makeup to create what looked like bruises. She did not testify in her own defence.
Ylen's story resembled a "cheap novel," prosecutor Suzette Samuels told jurors.
"She's lying through her teeth. ... This was unreal," Samuels said.
In final remarks, defence lawyer David Heyboer said police did not follow up on other leads and didn't go to Ylen's house for a close examination of what took place..........
