卷入 (juǎn rù) means 'to be drawn into' a negative event (scandal, dispute) — it emphasizes being involuntarily caught up, like being swept in. This contrasts with 介入 (jiè rù), which is an active, voluntary intervention, and with 陷入 (xiàn rù), which means 'to fall into' a state or predicament rather than an event. 牵扯/牵涉 (qiān chě/shè) focus on being implicated or connected, often in a web of relationships.
