。
She protested that she hadn't committed any crime.
Literal
She [topic-は] crime [object-を] have-not-committed [quotative-と] protested.
An indirect quotation: the と marks 罪を犯していない as the content of her protest, with no verbatim formatting. The polite 抗議する ('to protest, object') is a Sino-Japanese verb common in news, politics, and formal disputes — heavier than 文句を言う ('grumble, complain') or 反対する ('oppose'). 犯していない uses the negative continuous ~ていない to express 'has not committed,' the perfect-aspect reading: it covers any past time up to now. The whole sentence is a tidy frame for legal language — claim of innocence + verb of protest.
