A miscarriage sometimes happens because there is a weakness of the cervix, called an incompetent cervix, which cannot hold the pregnancy. A miscarriage from an incompetent cervix usually occurs in the second trimester. There are usually few symptoms before a miscarriage caused by cervical insufficiency.
Police perjury (or testilying in United States police  slang) is the act of a police officer giving false testimony. It is typically used in a criminal trial to make the case against a defendant who the police believe to be guilty when irregularities during the suspect's arrest or search threaten to result in acquittal.
Perjury is the crime of lying under oath. If, while under oath, you attest as being true to any essential fact that you know is false, you commit perjury. California law pursuant to Penal Code Sections 118 through 131 outlines the various ways you can be found guilty of committing this serious crime.
